Goodbye aliases: I use R as a programming language

removed "R" alias for using tee, also updated tee to use
~/scratch/tee.txt
update vimrc for better mac use
fix wrong undo directory
add some Rails.vim navigation commands
update bundles
small fixes to vimrc
add gitignore for non-shareable font files

Some of the font files I regularly use can't be shared (unfortunately),
so they gotta be excluded.
