Partial fix of the wx prefs. The modules settings are shown but not the libvlc ones. refs #918. (yes there is lots of debugs left)

- added OLESelfRegister in version resource (may fix reported security problems when registering ActiveX plugin)

- Oops, remove _wclosedir by mistake in previous commit. btw, the previous commit fixes #926 because utf8_loaddir() uses rewindir()

- since DIR* on win32 is mapped to a private data type, rewinddir(), seekdir() and telldir() must also be mapped to their vlc_ equivalent. Should fix ticket #926

*download the missing file
*build only the lib

* update libtwolame to 0.3.9 allows a simplification of our patch, as darwin9 linker appears to be as picky as MVS05's

* patch libtwolame and re-enable x264 as it was fixed upstream. all contribs are save for future darwin releases now. this commit deprecates all osx releases < 10.4 and the usage of GCC3 on Darwin. bootstrap will need further tweaking once 'gcc -dumpmachine' is updated to Darwin 9.

I wonder what I was thinking about.

bindings/python: removed vlc.Object code from the main vlc python module. This module should now be cleanly buildable from outside the VLC tree, given the public headers and appropriate libs are available.

bindings/python: moved vlc.Object (access to internal framework of VLC objects) to its own vlcinternal.Object module, which is not build by default.

as long as this does not cause infinite recursion.
Also fix a few really minor ToCToU errors.

Simplified mozilla headerfile detection for use with firefox-development headers and got rid of XPIDL/XPCOM checks from previous commit.
