This introduces an optional build-time dependency on
PackageKit-Qt.
Which package manager to start is currently handled via a
'removeApplicationCommand' config key which defaults to
Muon Discover, which will be moved to workspace soon. It's
been discussed to add a Default Applications entry for
this in the future, though; this small addition will allow
us to gather some experience with tighter package manage-
ment integration in Plasma.
Derived from original code by Aleix Pol.
REVIEW:120318
This version is a mostly-from-scratch reimplementation of
the Plasma 1 version.
Some minor-in-scope loose ends are left, both external and
internal to the code; check TODO for whether your issue is
already known.
