Add Tmux (#4562)

* Add Tmux

Being able to use a unified terminal setup between local and remote
hosts has some real advantages.

* Renaming is more important than reloading

* Self-explanatory, really

* Add alias for it

* Attach to last used session or start a new if we have none

* Just stick to n/p

* Make it a clean 10x

* We don't need this

* Keep similar fixes together

* Keep bindings together

* Hate looking at that 0

* Add way to refresh theme from its templates (when they've changed)

* Fix
