Bash: fix 'fg' alias to search case-insensitive.
Vim: if opening >1 file, put each in their own tab

I first created a new section in my .vimrc.after file for running
commands after Vim has fully loaded.

To this, I added a function I created which checks the number of files
passed to Vim on startup. If there is more than one, we create a new
tab for each buffer.
