[Bug 38910] Workrave should allow some events through (such as muting)

[Thomas M. Hinkle]

Public bug reported:

When workrave makes me take a break, it blocks *all* input. This means
that while on a break, it is impossible for me to e.g. mute the volume
if my phone rings or if I have an offensive song on when my boss walks
in.

Certain critical events should be allowed through workrave's block. This
should probably be user-configurable, but it seems like a decent start
would be to allow the following through:

Volume control (including mute)
Power off / Sleep / Hibernate
Fast-forward / Rewind (useful if you still want to control your music while on break from coding)
