major installation bug fix

Fixed major installation bug (non UTF-8 character).

Fixed pip installation from Anaconda; minor updates

• fixed CK execution with Anaconda python (Linux and MacOS) when installed via pip:
  pip install ck
  or
  pip install ck --user
• improved OpenME to call CK in dynamic websites
• added passing of $_SESSION, $_POST, $_GET to CK via OpenME
• added "Access-Control-Allow-Origin=*" to module:web to be able to access CK from local web pages
• added possibility to change default repo using "CK_DEFAULT_REPO" env var
• added flag --module_version to use different Python module (module{.{module_version}}.py)

minor improvements and fixes

• allowed local widget to fetch data from cKnowledge.org (or other) website: #93
• automatically print API of redirected functions (ck --help)
• improved module API printing
• added pypi download stats
• fixed minor problem with "ck renew repo" - now takes already existing UID instead of generating a new one

bug fixes from the community

This release fixes several bugs reported by the community:

• fixed minor bug in "ck rm" when deleting entries only from allowed repos (for crowdsourcing)
• fixed problem with wrong repo UID when repo is installed from zip archive
• added flag --all to "ck zip" to archive all files including .git
• fixed "ck add repo --zip" if zip contains Git repository (making it shared)

added several productivity functions and fixed a few minor issues

Changes:

• added "debug":"yes" to kernel for GitHub versions
• fixed minor bug in detection of minimal CK kernel version (important since current python3-ck in official Ubunutu 17.04 is quite outdated: v1.7.2)
• fixed tests to report the error detected by running ck.access() or equivalent
• testfix: stop testing 3.5dev and nightly Python, but add 3.6 which everyone uses
• improved auto-generation of a list of all modules and actions: http://cKnowledge.org/shared-modules.html
• made removal of \r in text files safer on Windows (across different Python versions)
• added TARGET remark to all CK kernel functions to show target audience (end users vs CK kernel developers). Used in "ck list_kernel_functions misc".
• improved recaching of repos (taking latest updates from .ckr.json into account)
• blocked copying of repositories to avoid duplication of CK entries
• added "ck python_version" to print Python version used by CK
• now when calling ck without arguments, it will print just a short help

added debug mode

• added CK internal var "debug". If set to "yes", print error when CK entries are broken or ignore them (now default). See ctuning/ck-tensorflow@c4ddfcd#commitcomment-25230616
• fixed minor bug when searching repo by UID when repo doesn't exist

minor bug fixes

Mainly minor bug fixes based on user feedback:

• fixed issue #80 (adding zip repo if starts with ~)
• fixed issue #81 (when renaming entry with data_name==data_alias, change it to the new alias)
• added flag --name (duplicate of --show_name) to "ck ls"
• fixed issue #82 (detecting name of repo from the zip filename)
• fixed repo renaming (now updates .ckr.json and recache repo properly)

added productivity functions based on user feedback and fixing minor issues

Improvements:

• added "ck cd {CK entry}" to open a new shell in a given CK entry
• added ck.compare_dicts examples
• fixed some self tests
• added safe recording of JSON (even if some keys are not serializable)
• printing user-friendly name (from info.json "data_name") when removing entries.
  Useful when deleting env entries (ck rm env:*)
• added more user-friendly configuration of internal CK variables via
  $ ck set kernel
  $ ck set kernel var.install_to_env=yes
• added safe deletion of CK entries with Git files on Windows
• automated adding CK .zip repos without questions

Started experimental functionality for stable CK repositories

Improvements in this version:

• added ck.debug_out(i) to print dict to console
• fixed strange warnings for Python 3.5+ on Windows and Linux (when installed via pip)
• fixed repo renewing on latest Windows (when access error to Git files)
• added ck show repo to show git status of all repos
• started highly experimental support for stable repos or different branches/checkouts (particularly useful for Artifact Evaluation to check out only stable repos)

fixing major bug when adding new module

Changes in version 1.8.7:

• fixed major bug with default license/author (to avoid crashing when adding new module)
• fixed minor bug in API when starting CK web service and viewing entry (wcid option)
• allow ~ in an archive name when archiving CK entries using 'ck zip ...'
