Add tmux.conf.local
Don't recursively map all the time

If users remap keys, the behaviour of the things set up in vimrc may change.

An example of this is the common remapping to switch `;` and `:`, which will
cause all of the keyboard shortcuts involving `:` to fail. Switching the *map
statements to their *noremap counterparts fixes this problem, by using the
original meanings.
