Expose outlineView property of file browser
Moving focus to file browser now select first item

This is only when using the special Navigate → Move Focus to File Browser (⌥⌘⇥) command and is mainly because there is no other visual feedback (other than the text view being rendered in its inactive state).

I could see sometimes not wanting a selection in the file browser, this however seems like a general problem (i.e. the solution should likely be to introduce a way to “deselect all”).
Look at entire line when auto-pairing characters

When inserting paired characters where the pair consists of the same two characters, we look if the line is already balanced, and if so, insert a pair, and if not, only insert a single character. Previously we only looked at what was left of the caret, though TextMate 1.x looked at the full line, which we now also do in 2.0.

Closes #508.
Allow disabling auto-indent for snippets

Snippets are normally inserted with indent matching that of the caret. This isn’t always desired, which is why TM 1.x allowed this feature to be disabled. This is now also supported for 2.0.

Closes #387.
