0.6.1 Minor but imporant release

Fixed a number of small but important issues and introduced a few new features:

-- #145 #149 Expand the types of files we can parse now that we have filesystem validation -- including hyphens, spaces, etc
-- #137 X mode! Select files with letters rather than UI, thanks @xavierbeynon
-- #143 Jump to line in sublime text, thanks @dufferzafar
-- #138 Use interactive shell to run script, which should fix zsh sourcing issues, thanks @hlian
