* Various minor bugfixes all around the code, but mainly in YoukiController and the main 3 display widgets, as well as some minute graphical changes
Merge branch 'master' of github.com:mderezynski/Youki2

Conflicts:
	api/CMakeLists.txt
	include/mpx/com/view-album.hh
	src/youki-controller.cc
* Fix outstanding merge conflicts
* Remove excessive comma in param list for render_icon() after removing the 'disc' parameter
* LyricWiki no longer supports the remote access of lyrics through an API for some while now; if we should ever find another free provider with API (unlikely), we can write a new wrapper. This wrapper is still from BMPx anyway, so there is no fantastic new code from Youki lost
* Remove widget components still coming from MPX/"Rimokon" which we don't use, and most likely never will use because they rely on TreeView usage, which is something we don't do for the main UI
* Delete the Coverart source preferences, since the order and which sources to use for the cover is hardcoded now (in this order: covers from inside the metadata, covers from Last.fm, files from the folder, e.g. "folder.jpg" or "cover.jpg", an finally covers from MusicBrainz, since their web API support is pretty bad). Being able to configure which sources to use AND even their order was very flexible, but really to confusing for the casual user; the current setup seems to be sensible. All Amazon cover sources were deleted, since I can't figure out their web API since the last change [sic]
* Remove unneded stock icons (for now, only the volume indicator icons, since I think that Gtk+ supports these in a sort-of volume control widget, and secondly our current volume control widget doesn't support, nor does it have space for, any kind of icons)
* Remove the horizontal-bar aniated throbber GIF; we currently don't need it in Youki, nor did we ever, and if we should, we should just write a similar one using Cairo anyway
* Delete the row-* icons, since we abandon the icon column in the tracklist in favor of more common menu items in the context menu instead
* Delete the quality icons, since they are awkward and there is really no good place nor is there really a need to use them (failed experiment)
* Delete the stars*.png icons for track rating. We currently don't have the option for manual track rating, and if we ever do, we should just render the stars with Cairo
* Forgot to actually remove the stars rating images
* Delete th so-called "title logo"; it was a small Youki logo displayed in the app's main window custom-rendered titlebar before we moved to an ordinary, default window-manager provided window title and frame
* Remove our lyrics APIs header, after removing the body file
* Delete the headers of all cell renderes, since we don't use TreeView
* Remove some headers of previously deleted widgets
* Remove jnetlib. It comes from BMPx, where we had a self-written GStreamer HTTP source element which used JNetLib as the HTTP library. Since a) there is at least one HTTP source element in standard gstreamer by now and 2) we don't support HTTP playback at the moment, and there are no currently known plans to do so, we really don't need this anymore now, do we.
* Remove the albumactions plugin. It doesn't work anymore at all, it uses completely obsolete and in Youki non-existent APIs.
* Remove the Python Last.fm Scrobbler; we have one written as a C++ plugin and prefer it.
* Remove lastfmvis as well; the idea is interesting, but the code is obosolete as well and uses the same ancient, in Youki not present anymore, APIs
* Kill the Pidgin plugin. KILL-IT. It has been superceded by Pidign-MPRIS, which is flying around there somewhere, and since most major media players these days support MPRIS (developed initially by yours truly), there is hardly any need for this plugin any longer.
* Remove OSD plugin. No one WANTS to see a huge, ugly, non-destop-standard-like ON SCREEN display on their, uh, screen these days. Trust us.
* Delete Playlist Tooltip plugin. It's kinda nice, but not something that fits in this way into Youki (plugin is also still from MPX)
