stripped leading "." from tab triggers per ST2 issue

Within Sublime Text 2, it seems there's an issue with starting tab triggers with special characters.

The snippets works with tab completion once you type the entire snippet, but the real time autocompletion popups do not work with any snippets that have these tab triggers began by special characters.

This branch simply removes the "." in front of the snippets' tab triggers to allow proper live autocomplete suggestion/popup.
