 Do not use vout_Request in aout_filter_t anymore but aout_filter_RequestVout.
 They have the same semantic but it will allows to control every vout creation
from aout.

NB, this highlights some reference counting strangeness.

Close ticket

This introduce a parseAndCreate function that creates all the needed buttons from a QString input.
This also introduce a next-frame button and the code needed behind it.

The code is suboptimal since it does save more often than when accept() is called. This will be fixed in the future.
