Removing kruft; adding Vundle; polish initialize

Apparently I played around with emacsmode at some point.  We'll just go
ahead and call that experiment concluded.  Removing the files.

Removing an old git plugin - using tpope's fugitive now.

Removing an old syntax-file-in-progress.

No more .vimrc in the repo (it's .gitignored now) - there's a
.vimrc.NoVundle and a .vimrc.Vundle.  The 'initialize' script is
responsible for symlinking the appropriate config to ".vimrc", for
syncenv() to put in place.

Exiting from 'initialize' on FATALs.

'initialize' now pulls/clones, and bootstraps Vundle for me.
Adding .vimrc templates to rsync exclude list
