Performance enhancements for getModeForSession.
The node-webkit stuff just works, and it's awesome.
Check extensions longest-first but only if filename has a period.
Merge upstream master.
Allow sandbox plugins to call commands. Closes #186.
Include "scss" as an extension for Sass

While some syntax highlighting might be slightly off due to the
differences between Sass and SCSS, it is certainly better than no
syntax highlighting at all.

I have tested the highlighting on a few .scss files, and the syntax
highlighting works quite well.
Support Scala syntax highlighting
Implement Help:Commands stub.
Add basic command list and keybinding.
Show current key binding for each command.
Change the styling a bit for readability.
Be explicit about keys that are unset.
Add some explanatory preamble.
More work on the standalone version, which actually really starts to
come together now. Even has some uber simple CLI support now.
