---------------------------------------------------------------------------
Changes from v0.2 by Darren Owen aka DrO
* Added Alt+A global shortcut to toggle the album art window
* Album art window is now included in Winamp's ctrl+tab feature (broken in some 5.5x builds)
* Double-click will now open the folder (like the native album art window does)
* Changing menu id to be dynamic rather than hard-coded to show use of IPC_REGISTER_LOWORD_COMMAND
* Made background colour match the media library album art views (override with waBkClr=1 in the plugin's ini section)
* Made compatible to deal with Winamp being minimised on startup so the window won't appear briefly
* Implemented winampUninstallPlugin(..) support
---------------------------------------------------------------------------
Changes from v0.3 by Darren Owen aka DrO
* Added localisation support (with example en-us language file included in the installer)
* Adding an option to show the album art when clicking on an item in the playlist editor without having to play it
* Fixed the main menu item not working via the system menu
* Plugin will now only work on 5.53+ clients to ensure the Alt+A global shortcut will work (bug-fix for v0.3)
* Fixed issue with api.h not containing all of the required headers (only affects compiling source code)
---------------------------------------------------------------------------
Changes from v0.4 by Darren Owen aka DrO
* Added detection of being used under a modern skin so the album art window and menu item can be automatically hidden (default: on)
* Added in ability for the tracking action to work via the keyboard actions along with button clicking
* Tweaked the menu item text so the items (at least with en-us translations) is better consistant with the rest of Winamp (if that's possible, heh)
* Added config menu into the Winamp preferences so it's possible to access the options when the album art window isn't shown
