Updated plugins
Prefer mapleader to be ';'.
mkdir plugin/ && wget http://cscope.sourceforge.net/cscope_maps.vim
Added listchars.
+let g:airline_theme='solarized' to be visible under OSX.
Added map F to ShowAllFuncNames(): List all function names of current file.
Avoid warning in Zenroom on newer Vim release.
Linus Torvalds style:

	Tabs are 8 characters, and thus indentations are also 8 characters.
	There are heretic movements that try to make indentations 4 (or even
	2!) characters deep, and that is akin to trying to define the value of
	PI to be 3.
Added tw for Markdown and gitcommit.
