Removed several functions from init-functions that I didn't
actually use.
Lots of other cleanup.
The variable "is-vim-user" in init.el controls whether or not
evil packages should be installed and configured.
* Moved load-file-if-exists to init-functions
* Added init-misc.el for random things that don't fit anywhere else
* Never any tabs, ever. Go away!
Bindings:
* quit Emacs -> C-x r q ("real quit")
* delete-frame -> C-x C-c
* make-frame -> C-x C-n
