[vim]: added extradite

Although I find myself using Gitv more often... so I might remove this.
[vim]: explicitly set some indenthtml.vim settings
[vim]: guifontpp mappings
[vim]: Gitv show preview of selected commit on launch
[vim]: use spaces in vimrc
[vim]: use +/- for window size again
[vim]: disambiguate :E vs :Ex (NetRW / Extradite)
[vim]: :set confirm
[vim]: vundle update
