Reboot vimrc, starting from scratch (almost)

Too many plugins, too many problems...
Make things much messier, in search of a base config
Add more junk to muck things up
Heading back toward the original config, I guess...
Disable stuff to work on fixing jedi

Figured out jedi and neocomplete clash with each other, so try to disable
neocomplete for python. This autocmd doesn't seem to always work, though.

While I was at it, put back in buffet until I am more comfortable with
unite.vim

Fixed history size, gave in on clipboard setting and enabled commentary
plugin.
Add several plugins after testing

* signify (working on windows)
* tagbar (need to test on larger codebase)
* easytags (works after creating local tagfile)
Add whitespace highlighting
speed improvement, try to get snippets working
Update neobundle invocation according to latest docs
