ServiceName: Try to fix the <n/a> GSOD issue

Thanks BugLess
GMEPG and ChannelSelection, ServiceEvent -> Service.

This avoids conflicts in combination with the EPGSearch, AutoTimer
and TMBD plugin which otherwise sometimes result in lost key-remappings.
MediaPlayer: Remove more not required code
Navigation: Continue playing old service when incorrect PIN

When incorrect PIN is entered for the parental check previously
the screen went black. Now the current played service continued to
play and when that service is available in the channel list it will
also keep/set the focus to it. Why should we give a black screen here
This is also valid when the parental control is in timeout.
Not goto current service when going to userbouquet
servicedvb: use stream type -1 when using audio pid as 'timing pid'

using the audio stream type causes tstools to parse audio pes,
and look for video start codes

issue found by betacentauri
UsageConfig: use the same range for all subtitle delay settings
GetEcmInfo finetuning parsing of statusfile.
ChannelSelection: Skin support for Editmode and EditReference.
ChannelSelection: Add support for the Event source.
EventView: Add support for Service and Event sources.
EventView: Add support for FullDescription.
Protect timeshift at least during normal zapping

But still the movieplayer, scanning for (new) channels and
a lot of plugins might abort a timeshift in progress
Revert "Protect timeshift at least during normal zapping"

This reverts commit f857ad6bd9c6720980257848e79da862dea12a3d.

Sorry I committed this as accident... there are still side
effects
