Disable Qt keywords completely

Previously we had the policy that no qt keywords were allowed in headers
that may be included by users. However since there was no automatic test
verifying that in some places keywords were still used.

This now disables qt keywords completely, also in tests and examples. Qt
keywords are in general no good or really good idea as they even
conflict with the standard library (`emit` at least).

In some cases in the examples I just removed the slot tag if the
functions didn't need to be slots (anymore).

Closes #503.
