ugly dirty horrible thing so that text/xml files don't get labeled as text/html (and .xml files will now be parsed by VLC)

- Move acl.c to a more appropriate location

- Don't force a port on the slave side (that was not needed)

and other cosmetic fixes

* complete l10n support

The usage of the logo-filter doesn't work here, but that might be because of my strange PNG-files. I'll investigate this tomorrow.

It would be nice if some of the OSX-devs and testers could check whether everything works as expected, whether you are able crash the entire thingie, etc.
Note that on-the-fly activation of filters doesn't work (this needs the vout-rework scheduled for 0.8.5).

* removed the controls used for fixed positioning, because they conflict with the relative controls and aren't used by most of the users anyway
* fixed 10.3 compatiblity

still TODO:
- implement the logo and time controls completely
- l10n
- FIXMEs

Fix a bug in delete

* modules/access/rtsp/rtsp.c: fixed major bug in realrtsp access. Some incoming data would occasionally be dropped.
