Commit mutt configuration and changes to bash and vim.

Have started using it to access Gmail. I don't intend to completely stop
using the web interface, but for everyday emailing I do like it quite
a bit.

.offlineimaprc and .netrc are also needed for this to function properly,
but they contain my Gmail password in plaintext so I cannot include them
here.

Have added an 'em' function to bashrc that syncs everything and then
fires up mutt, and a \s function to vimrc that helps insert boilerplate
text when writing an email (mutt calls vim when writing mail).
Add some auxiliary mutt files I forgot.
