Setup YCM + some gitignores symbolic links
1. Set up gr8 YCM plugin, but still need to configure it somehow. It doesn't work properly. Maybe I'll delete it later, maybe turn off. And maybe will use.
2. Set up .argparse, .frozendict & .vim-matchit gitignores in dedicated Gitignores directory with symbolic links. Cause I don't like error messages all over my submodules.
3. Color of popmenu changed in .vimrc from pink to black :)
