Title: Add subword cursors - take 2

Fixes #1982 and an alternative to #3961. Also, hopefully can used with atom/vim-mode#377.

I haven't added keymaps yet. But maybe:
```cson
'.platform-linux .editor, .platform-win32 .editor':
'alt-left': 'editor:move-to-previous-subword-boundary'
'alt-right': 'editor:move-to-next-subword-boundary'
'alt-shift-left': 'editor:select-to-previous-subword-boundary'
'alt-shift-right': 'editor:select-to-next-subword-boundary'
'alt-backspace': 'editor:delete-to-beginning-of-subword'
'alt-k': 'editor:delete-to-end-of-subword'

'.platform-darwin .editor':
'ctrl-alt-left': 'editor:move-to-previous-subword-boundary'
'ctrl-alt-right': 'editor:move-to-next-subword-boundary'
'ctrl-alt-shift-left': 'editor:select-to-previous-subword-boundary'
'ctrl-alt-shift-right': 'editor:select-to-next-subword-boundary'
'ctrl-alt-backspace': 'editor:delete-to-beginning-of-subword'
'ctrl-alt-k': 'editor:delete-to-end-of-subword'
```
Sorry for changing most lines in text-editor-spec.coffee. I had to add a separate fixtures file for better tests. If there is a better way than wrapping everything in a describe block, than let me know. I could make a separate file, but that's probably not what you want.

Also, I can't figure out how to go left on the first line when there is only white space, see cursor.moveToSubwordBoundary(), /^[\t ]*$/ isn't working.
