* forward-port of all eyetv relates sources in my branch
    - this stuff is highly unfinished; needs much more work and testing
    - don't be surprised if you don't see anything when trying it out, this port is basically a big reminder for me to keep working on it ;-)
    - the access module is probably going to be ported from CoreFoundation-driven C to Cocoa-based Obj-C
    - everything will be 10.4-only, since EyeTV is only available this way as well
    - the plugin to put into EyeTV is compiled in UB-mode by default and incorporates Public Domain code provided by Elgato Systems GmbH
