Subject: [PATCH] bugfix: dont source file based snippets more than once

Set the s:did_<filetype> flag after reading in
file based snippets. This prevents snippets getting read in more than
once.

Move the code that checks for file based snippets out of
after/plugin/snipMate.vim and into plugin/snipMate.vim. Refactor this
code into functions for readability.
