0.9.0

• fixed annoying issue where initial scroll position was set incorrectly (when the row was in the first half)
• fixed issue #140 - add feature to hide columns
• fixed issue #31, #139 - ctrl+tab, ctrl+shift+tab, alt+1, ..., alt+9 (on linux/windows) is not longer consumed by handsontable
• fixes issue #75 - watch files outside of workspace for changes
  • removed chikidar as dependency, vs can now watch all files
  • because the timing when a change is detected and when file model (vs code) is updated is not the same across platforms, we have to use vs code's own file change events
    • onDidChangeTextDocument behaves the same way for all platforms but is always fired after the file was changed (on every key stroke)
    • however, we still need a file system watcher because when the user closes the source file, no onDidChangeTextDocument event is fired anymore (until openTextDocument is called again)
    • to detect if the file was really changed we have to compare the file content with the last known content (so we have a full copy of the file content in memory)
      • this is because we need to know if the change was triggered by this extension or by another program (if last known content == current content then the change was not triggered by this extension)
• changed logo
