vim: remove unused plugins
vim: stop confusing pairing partners like @s0enke

By not changing vim's default regex handling.

Originally, the intention was:

	The first two lines fix Vim’s horribly broken default regex “handling”
	by automatically inserting a \v before any string you search for. This
	turns off Vim’s crazy default regex characters and makes searches use
	normal regexes. I already know Perl/Python compatible regex formatting,
	why would I want to learn another scheme?
