Add snippets for subject and specify
Add syntax highlighting for steak keywords (feature, scenario).
Simplify snippets (it, desc, con), add source.ruby.rails.spec scope. Delete unused variants.
Customize run commands (names, keybindings, scopes, zeus).

They now have better names and are available in source.ruby.rails.spec scope, too.

New Keybindings: Cmd-Alt-R = "Run Again", Cmd-Shift-Alt-R = "Run Selected Files" (available in ALL scopes).

"Run Again" does a real rerun of the last run - whether it was a single context, a single file, or multiple files.

All run commands try to use "zeus" if available and fall back to "bundle exec" else.
Make let snippet available in source.ruby.rails.spec scope.
Fix running specs twice if zeus is available but some specs fail.
Run rspec via binstub, if available.

This is the preferred versions (it supports e.g. spring: https://github.com/jonleighton/spring). If no binstub is available, fall back to zeus. If zeus isn't available either, fall back to bundle exec.
Nicer formatting for info output.
Fix run_rspec to work with recent TextMate versions.

Working directory is no longer the project directory, so we have to set it ourselves.
Add command 'Run Current Context in Terminal' (^R)

Very useful for debugging specs with pry :-)
Do not echo rspec command line in textmate output window.

The idea behind this feature was to allow easily rerunning the same command in the terminal by just copy-pasting. This is no longer necessary now that there is 'Run Context in Terminal' :-)
