Adding cache files and binary files

all file extensions associated with sublime text such as:
```
.stTheme
.sublime-project
.sublime-snippet
```
etc…

Followed cache (e.g. `.stTheme.cache`) can be ignored, sublime text re generates these hides are needed, no problem. The same applies to extensions `.pyc` which are binary code packages python, sublime text re generates.

sorry for my bad English.
