Save last used transcoder format with the mimetype instead of the extension.
ogg vorbis and ogg flac have the same extensions (*.ogg) and therefore the wrong item in the format combobox might be loaded.
Network remote can now transcode lossless files before sending them to the remote.
- It is configurable in the settings.
- Any format can be chosen that is supported by the transcoder.
- The status of the transcoder is send to the remote.

- Transcoder format settings have now a postfix so we can define mutliple transcoder formats and use them separatly. Here one for the normal transcoder and one for the network remote transcode. You can pass the postfix in the constructor.
- Fixed Transcoder crash (was introduced with the gstreamer1.0 merge, decodebin doesn't have a "new-decoded-pad").
- Transcoder emits the output filename as well on "JobComplete" signal
- Transcoder can now convert a file to a temporary file ("AddTemporaryJob")
Try to fix windows build.
Send correct total file size if files were transcoded.
