Revert "frontend: prefer DVB-T2 when both are available."

This reverts commit 14da57c433d243007ed3a5114b609dfaaf1cc400.

T2 transponders will always have System_DVB_T2.
If a transponder with System_DVB_T_T2 makes it into the lamedb,
this means no fallback to T2 has been made during the automatic scan,
so we are dealing with a T transponder.

So we should definitely not prefer a T2 tuner for
System_DVB_T_T2.

eDVBScan: fix T->T2 fallback

broken by 8d8ca4272ee1da26a4edf8867e171b7626f352ae

Instead of having a fallback when 'system' was
not specified in terrestrial.xml, we were doing a
fallback when scanning T2 transponders instead.
eDVBDB: avoid storing System_DVB_T_T2 in the lamedb

eDVBFrontendParametersTerrestrial::System_DVB_T_T2 is only
used during automatic scan, resulting transponders should
have either T or T2.

ChoiceList: Only load PNG when key is defined

As suggested here:

Use a format-string instead of concatenation. This allows any printable
object to be used as key name (e.g. numbers) instead of forcing key to be
a string, it's more efficient and it won't crash when key is something else.
Downloader: replace import of urlparser

Not smart to "import" it at each call.

Add option "Network scan" yes/no for Automatic scan

If not, it is much less time to scan.

Additional check on the availability of the satellite

e.g. tuner use settings "advanced"
