Fast CtrlP matcher based on python

Performance difference is up to x22, look those profiling log:

Default matcher:

FUNCTIONS SORTED ON SELF TIME
count  total (s)   self (s)  function
    3  17.768008  17.610161  <SNR>102_MatchIt()

With Py Matcher:

FUNCTIONS SORTED ON SELF TIME
count  total (s)   self (s)  function
    3              0.730215  pymatcher#PyMatch()

To install this plugin you need Vim compiled with +python flag and version 7.4+ (because of vim.bindeval like python functions. It can be rewriten via your pull request, to support vim < 7.3):

vim --version | grep python

If you still have performance issues, it can be caused by bufferline or another one plugin. So if it caused by bufferline you can switch to airline and setup this option:

let g:airline#extensions#tabline#enabled = 1
