Yet another x264 contrib patch for win32

* FFMpeg reactivated the WM3-codec. The patch is now useless

* More useless interaction cleanup
* Small fix for make beautifier

* interaction.c: always show errors through the interaction framework, even if the user disabled its usage
* macosx/*: minor clean-up

* removed the old panel which used to show msg_err completely (hopefully) and added a new menu entry to show the collective errors/warnings panel by hand. Additionally, this panel got a details button now. (thanks to thedj for the idea)

  Something went bad. Sorry.

removed in r16159 by fkuehne and fix the nightlies.

 - this dupes some code from the playlist demux (FindItem).

 * JAVA_HOME is set
 * a java compiler compiles

Typo fix in modules/stream_out/bridge.c

* gnutls needs -lintl ldflag with newer versions. It's so nice if packages keep track of what libs they use....... hint hint

osx/intf.m: don't show msg_err's in the OSX GUI anymore. Localised errors/warnings are shown by the interaction framework now.
wx/interaction.cpp: another WX compilation fix

    - intf_UserFatal takes an addition bool-argument now to set whether the error message will be blocking in the interface or not (so TRUE = blocking)
    - intf_UserWarn is always non-blocking and is used to check important, localised warnings to the user
* wx: a compilation fix, but no update to the current API
* osx: complete implementation of the interaction framework using some Carbon (!) functions, because the needed icons aren't accessible through Cocoa. Regrettably, I had to add yet another nib-file to keep the code clean and readable.

The Error-dialogue is no longer re-usable (so the specific ID was removed). The interface needs to keep track of the reported errors and warnings. Thus, it may discard them as requested by the user and doesn't need to care about the core.

Misc fprintf cleanup
