feat(shell): integrate the emacs better into the terminal

There a quite a few fixes and feature here to make the terminal experience of
emacs better. Most of this is only enabled when running in the terminal.

1) Better tmux integration with navigating between splits and also highlighting
the active window between emacs and tmux so you can better see the active window
you are working in.

2) Mouse and clipboard support through the x window manager so "yank" copies
text into the system clipboard

3) Changing the cursor style between insert and normal mode inside the terminal
this is not the case in default evil mode.
