Merge #342

342: Snippets: change hard-coded 4 spaces to tab charaters r=ehuss a=Uupis

When using snippets, Sublime Text expands the tabs based on user preferences. This way users who use 2-space indentation will get 2 spaces when using a snippet, users who use 4-space indentation will get 4 spaces, and users who use tabs will get tabs. 

I realize that the vast majority of Rust code seems to be 4-space indented, and that looks to be the encouraged style, but, for my own code, I prefer 2-space indentation, and I don't think this change necessarily goes against the 4-space style. The only imposition for future changes is that multi-line indented snippets need to be saved with tab characters.
