Update install.sh: add vim-plug compatability
Update vimrc: change plugins to vim-plug syntax
Update vimrc: add post-install commands for YouCompleteMe & vimproc

Vim-plug adds a feature that allows you to execute commands in
specific plugin directories to aid in the installation of plugins. I
added two of these such commands to YouCompleteMe and vimproc as they
both require post-download installation steps.
Update install.sh: remove ycm and vimproc sections
Update install.sh: update for vim-plug syntax
fix vimrc: YouCompleteMe post-update hook command

I changed the post-update hook command for the YouCompleteMe plug-in
from ./install --clang-completer to ./install.sh --clang-completer.
