Updated plugin submodules

In preparation of some big jump for clang_complete and ultisnips.
BIG update to clang_complete and UltiSnips

- TODO: remove the "!" flag from my own custom snippets (it was replaced by
  priorities).
- UltiSnipsEdit doesn't work, even though snippets, unite/neocomplete sources
  do...
- Add a map to call ClangGotoDeclaration, which is now thankfully public.
Add note to self about keys for operators
Add and configure endwise and smartinput_endwise

Added both, but only smartinput_endwise is actually active. I want to easily
evaluate each, and I want to check the code of endwise, so if I disable via
pathogen is not easy to find through Vedit, etc.
