First attempt: SaltStack support for Sublime Text

Provides Sublime Text snippets for a variety of stack commands
(including file, pkg, host, network, user and group). Snippets and
syntax highlighting are also provided for Jinja (using code forked from:
https://github.com/jpvanhal/sublime-jinja2).

Preliminary syntax highlighting for SLS files is also provided simply by
calling Sublime Text's built-in YAML support.
Change of plans - use standard install repo

We can submit this package to the standard repository for Package
Control, but have to take it one step at a time. Once these changes are
accepted upstream, I'll make the submission to Package Control.
Force spaces instead of tabs for SLS/YAML files.
