Do not startup to standby when the UI is restarted

Thanks IMS for reporting this
Small optimalization for my previous commit

As misc.RestartUI config needs only to be saved in Standby.py when it is
set to true
Never startup to standby when user initiated some restart.

Not only for restart enigma2/UI, but also for update software, reboot,
update fontprocessor.

Somehow suggested by Dima73.
During startup of enigma2 start progress at 0% instead of 50%

As it makes no sense to start this at the half, at least for the latest
boxes.
Also do not startup in standby when we have an exception in python code
Fix some intend mixed spaces tabs stuff
Do not stop a service when in standby the current time is unknown.

Allow one minute to try to obtain the current time from the currently
tuned service. When this is still not possible we consider that the
specific service could not be tuned. For startup to standby the box will
be put in standby via a notification and then afterwards a service is
started. this patch will also stop this started service after the box is
put in standby after one minute, which also allows the current time is
correctly set.
Check if current date is known by checking year > 1970

It seems that the drivers from VU could put the box before 1970, so
comparing with != 1970 is not a good check if the current date is known,
so I replaced that by > 1970.
It is one services that is stopped, not more services.
Some finetuning regarding the standby and current time available changes
Correctly stop timers in Standby.py

Thanks Dima73
