New OE2.5 Update - 17.02.2017

Update: ennigma2 4.3.0r27

- improved handling of multicast services
- Virtual Keyboard:
   - override skinned zPosition so it's always sitting on top
   - hide input helper when VirtualKeyboard is open
- (Music) Tags:
   - fixed missing tags when streaming music
   - fixed broken parsing of tags with umlauts
- EpgSelection / GraphMultiEPG:

- fixed UPnP mime type detection for subtypes of audioItem and videoItem

- fixed handling of more than two WHERE_AUDIOMENU plugins
- dropped TuxboxPlugins - it's been broken since 2008
- Components.VolumeControl:
   - added config.audio.volume_stepsize which allows setting the volume control stepsize to a value between 1 and 10 (default remains at 5), currently not adjustable via UI
- implemented userAgent/transportHeader handling for DVB services
- added some new blending modes requested by dr.best
- generic python code cleanup and stability fixes
