Support for primary/selection clipboard

Registered by Oliver Sauder

Basic implementation ala Parcellite.

We should decide how the clipboard items from the primary selection and the clipboard itself are represented in the application indicator.

Possibles ways:
* Bold -> from clipboard; italic -> from primary selection (like parcellite)
* [K] -> from clipboard; [M] -> from primary selection (like glippy)
* icons as indicator
* no difference
