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

create as many presets as you want based upon the respective current selection and remove any (including the defaults), if you don't like them. Reset VLC's preferences to get the original set back. There is no way to edit existing presets and this isn't scheduled for now.

This was only useful when we had several URLs to handle

macosx: use structures in NSUserDefaults to manage the EQ presets to prepare the implementation of custom EQ sets

Initially, the presets are fetched from the audio filter. After the import, only the NSUserDefaults structures will be used.
