Add .ssh/config
Add .ssh/config to install.sh
Note the Vim config works with Vim 7.4
Use new Vim 7.4 features where available

Vim 7.4 adds special 'shiftwidth' and 'softtabstop' values to have them
follow the values of 'tabstop' and 'shiftwidth' respectively.  That's a
handy feature -- if we're running a suitable version of Vim, use it.
Merge branches 'ssh' and 'vim-7.4'
