Move contents of .vim/bundle to .janus

In preparation for a Janus installation.
Move the rest of my .vim files to .janus

Except for molokai, Janus will have that.
Move .vim/{backups,swaps,undo} to .vimtmp, remove pathogen

Because Janus uses .vim.
.vimrc -> .vimrc.after
Add Janus!
Remove vim plugins that are duplicated by Janus
Ignore home/.vimtmp
