Collection of fixes (Mainly fixes for windows)

Dear Joker developers,

First, thank you for creating Joker and making its source available on GitHub. It's a very interesting project!

Here you will find a pull request that:
- fixes issues related to Windows,
- fixes display issues (filtering of the video and deinterlace settings)
- fixes LTC syncing (problably related to runtime behaviour of PortAudio on Windows)

These commits all look straightforward to me. (I have a couple of other commits that may need a little bit more attention, related to timecode issues and OpenGL optimizations, but I will only submit them later if this first round is satisfying to you).

Please do not hesitate to ask for détails on these commits, and be sure that I would be happy to see this pull request accepted !

Best regards,

Timothée

Ok!

I cannot find "logLevel" ? Is it "logMask" maybe ?
