Update enigma2 po files
PositionerSetup: add function to find unused positioner index position

By rhinoceros
AudioSelection: Prevent for GSOD in MediaPlayer
MediaScanner: Simple Messagebox and timeout when no playable media is found
frontend: set some default min/max frequencies for simulated frontends

this should fix using simulated frontends (e.g. timer conflict detection)
AudioSelection: Remove duplicate if .. len(..)

"x and len(x)" == "x"
empty list, tuple or string is also False.
RecordTimerEntry: Add __repr__ method

This makes "print entry" output something useful instead of a class name and pointer.
GraphMultiEPG: Fix GS after leaving GraphMultiEPGSetup Screen, when no service is currently playing

Harddisk: do not put removable block devices to sleep
Demux: Less blocking when in streaming mode

When streaming, the intended effect is that if the remote cannot keep up,
drop whatever we were sending, and wait until the remote accepts data again.
Also use less buffers, no need to increase the latency.

This does not work as expected. For example, start VLC and pause it (this
will simply stop reading from the socket). Wait for the overrun, and unpause.
The streaming will sort of resume but remains seriously broken, and enigma
fails to get out of a sort of "fail" loop.

The behaviour is a bit better than before, where it basically kills enigma
when the remote just stops reading or doesn't read fast enough. So that's why
I'm committing this even though it's broken.
de.po: Update German Translation Due to latest locale LC_TIME Changes and commits

SoftwareManager: cosmetic code reduction
PositionerSetup: fix message string (cosmetic)
Update dutch translation
Fix dutch translation
Harddisk: init self.is_sleeping in the constructor

Fancontrol2 is checking this member, resulting in an exception
FixedMenu: Fix GS when trying to access a invalid Tuple

Eg when using CutListEditor Plugin and it's menu selection to avoid:
IndexError: tuple index out of range
I did add the sanerty check in to avoid a possible other GSOD in case
this object is used elsewhere while selection could be still None
PicturePlayer: Fix crash when closing settings screen

"setConf" lacked a parameter.
And a bit of code cleanup.
Harddisk: move initialisation of last_access and last_stat into the constructor

Fancontrol2 seems to be using various (private) Harddisk members.
So if some are not initialised, because we are not running a sleep
timer on a device, it would crash.
