lib/theme: new `_bash_it_appearance_scm_init()` 

Wrap init code in a function and call the function immediately. Several plugins do this, and it allows us to more easily implement a hooks-based system in the future.

Alsö, avoid external binary `which`. Use built-in `type -P` instead. Uppercase `-P` forces a path search to avoid hashed matches and functions/aliases and whatnot.
