- ChanSort didn't work properly for Turkish (and other system locales) that don't translate ".bin" to uppercase

Browse Source 
".BIN" and ".BIN" to lowercase ".bin".
- Philips: Removing a channel from a list is no longer possible (because it is not supported by the TV's import).
  When saving a file, all unsorted channels will be placed at the end of the list.
- support for Philips Repair\mgr_chan_s_fta.db lists is now read-only. Files can be used as a reference list,
  but modifying them won't be possible.

* This serializer is used for the channel list format with a Repair\ folder containing files like channel_db_ver.db, mgr_chan_s_fta.db, ...
* The .db files are proprietary binary files, not SQLite databases.
* So far only the mgr_chan_s_fta.db file holing DVB-S channels is reverse engineered, the offsets are defined in PChanSort.Loader.Philips.ini
*
* Unfortunately modifying the .db files does not seem to be enough. The TV also depends on channel data in the FLASH_* files, which I don't know how how to edit.
* Therefore lists of this format can be read as read-only reference lists, but modifications are disabled.

@@ -14,11 +14,19 @@ namespace ChanSort.Loader.Philips
This loader supports 2 different kinds of XML files from Philips, the first in a "Repair" folder, the others in a "ChannelMap_100" (or later) folder
Example from Repair\CM_TPM1013E_LA_CK.xml:
This "Repair" format comes with a visible .BIN file and a .xml file that has file system attributes "hidden" and "system".
The TV seems to use the .BIN file as its primary source for setting up the internal list and then applies the .xml on top of it to reorder channels.
It uses the "oldpresetnumber" from the XML to lookup the channel from the .BIN file and then apply the new "presetnumber".
The .BIN file itself is compressed with some unknown cl_Zip compression / archive format and can't be edited with ChanSort.
Deleting a channel is not possible by modifiying the .xml file. Omitting a channel only results in duplicate numbers with the TV still showing the missing channels at their old numbers.
<Channel>
<Setup oldpresetnumber="1" presetnumber="1" name="Das Erste" ></Setup>
<Broadcast medium="dvbc" frequency="410000" system="west" serviceID="1" ONID="41985" TSID="1101" modulation="256" symbolrate="6901000" bandwidth="Unknown"></Broadcast>
</Channel>
Newer channel lists from Philips contain multiple XML files with a different internal structure, which also varies based on the version number in the ChannelMap_xxx folder name:
<Channel>
<Setup SatelliteName="0x54 0x00 0x55 0x00 0x52 0x00 0x4B 0x00 0x53 0x00 0x41 0x00 0x54 0x00 0x20 0x00 0x34 0x00 0x32 0x00 0x45 0x00 " ChannelNumber="1" ChannelName="0x54 0x00 0xC4 0x00 0xB0 0x00 0x56 0x00 0xC4 0x00 0xB0 0x00 0x42 0x00 0x55 0x00 0x20 0x00 0x53 0x00 0x50 0x00 0x4F 0x00 0x52 0x00 " ChannelLock="0" UserModifiedName="0" LogoID="0" UserModifiedLogo="0" LogoLock="0" UserHidden="0" FavoriteNumber="0" />
