UltiSnips 3.0

• Organisational changes: The project is now hosted on github. Snippets are
  now shipped separately - please track honza/vim-snippets.
• UltiSnips is now a drop in replacement for snipMate - it parses snipMate
  snippets and expands them emulating snipMates smaller feature set.
• Filetype tab completion for UltiSnipsEdit.
• UltiSnipsEdit now only edits private snippet files. Use UltiSnipsEdit! if
  you want to edit shipped files.
• New option 's' which strips trailing whitespace before jumping to next
  tabstop
• New option 'a' which converts non-ascii characters into ascii characters
  in transformations.
• New keyword in snippet files: priority defines which snippets should
  overwrite others. This deprecates the '!' option.
  UltiSnips-adding-snippets
• Remove common whitespace of visual line selections before inserting in an
  indented tabstop.
• Support for overwriting the snippet directory name on a per buffer basis
  to support per project snippets. UltiSnips-snippet-search-path
• The keymaps for jumping in snippets are now only mapped when a snippet is
  active, allowing them to be used for something else otherwise.
• Expanding and jumping no longer overwrites the unnamed register.
• Integration with Valloric/YouCompleteMe and Shougo/neocomplete.vim.
• Other plugins can add sources for snippets to create snippets on the fly.
  UltiSnips-extending
• Vim functions now indicates if it did any work.
  UltiSnips-trigger-functions
