Rewrite to use native tmux config rather than bash

[kjnsn]

Previous versions have used bash extensively to generate options that are then passed into tmux. The tmux config language provides powerful support for customisation using format strings. Using format strings would greatly simplify implementation and allow for easier end-user customisation.

Development is occuring on the tmux-native branch.
