New methods are provided to:

 - get the available equalizer presets;
 - get the available frequency bands (useful for creating a UI);
 - create a new default equalizer, or create a new equalizer from a preset;
 - release a previously created equalizer;
 - get/set preamp and individual frequency amplification values;
 - apply equalizer settings to a media player.

Equalizer settings are persistent, can be made whether media is currently playing or not, and will automatically be applied to subsequently played media.

Podcast module does not have previous session urls loaded when a
change request is called first. As this list is also saved on any
change, the original list is lost.

No way to reproduce bug case.
Fixing by removing all the code.

This reverts commit ddf9e6da.
This reverts commit c7ab9f11.
This reverts commit 541c1d97.

Zero items count means there is no static list. But there could be a
dynamic list. Qt should not access config items directly.

Some RTSP implementations (Foscam H.264 IP cameras) return HTTP/1.1 501 Unimplemented on OPTIONS requests. Don't fail out in this case; just continue and assume GET_PARAMETERS is unsupported.

I have a Foscam h.264 IP camera with a very strange RTSP-over-HTTP
server, and I wanted to get VLC to play it back.  Here's the patch
to VLC; I also had a patch committed to live555 to resolve a few
other issues, and that's available in live.2012.09.13.tar.gz.  Do I
need to submit a patch to contrib/src/live555/rules.mak to pick that
new version up?  Or is there a special process for that?  Or should
I just wait a little bit?  :)

and move detached_titlebar_view stuff to detached window

simplifies code and is more precise

This way, you can keep multiple sets of filters with their respective values.

This implementation goes beyond custom EQ presets, which can be configured separately.

Tradeoff for large inserts that can cause heavy disk I/O due to the
transactions. ML is a non-critical database.

Remove stuff that do not make sense for a portable folder

Sqlite can't make use of indexes on LIKE queries.
It always results in a full table scan.

This way, you can keep multiple sets of filters with their respective values and switch on-the-fly

Close #750 too

moved custom zoom/minimize/close implementation, added new file for window related stuff
fixed minimize / close support for !video-deco window

macosx: decouple !video-deco from detached video window and allow changing this setting without restart
