Add theme function

Browse source 
The theme function provides a quick but temporary switch to a specific
theme.

Themes can be applied with `styler theme [themename]`, they will be
instantly applied to all enabled applications. They will be lost on
restarts of the application or machine however.

Themes can be applied permanently with `styler set [themename]`, they
will be written into the application's settings. This *will* change
things in your local filesystem, so be wary. Generally, processors
should take the least invasive approach and use inclusion to append the
theme to the application's other settings.

But be *careful* with this option, and when in doubt double-check what
the processors you have installed do before losing your settings.
