lastfmcoverart plugin for exaile works with old lastfm api

Hi, I rewrote the plugin to support the new API, so it downloads bigger covers.
But the plugin isn't matured yet. I'm a beginner, so I'm grateful about any help.
Why the images aren't saved in the album's direcory. I don't change it, because I suppose there is a reason.

I improved the plugin, so that it searches for the track title, if the album weren't found.

Looks OK to me, but whose API key is that? I think we should use
Adam's (it may be in 0.2.x), and it should be made a constant.

Targetting 0.3.1.

I copied the API key from the example url. http://www.last.fm/api/show?service=357

I fixed a small bug, adjust the version number and add myself to the authors.

I've registered an API key for Exaile on last.fm: 3599c79a97fd61ce518b75922688bc38

Is it better if the user can select the cover size out of a list. (small, medium, large, extralarge, mega)
What do you think about to convert the cover into a certain image format, if desired.

I don't know what those size categories correspond to in terms of pixels, but if we can't sensibly pick a default that will work for basically all users, then I have no problem with making it an option.

Conversion to a particular format will only be relevant if we add support for saving downloaded art to other locations. As long as the images are only used internally, I don't see any point in converting them, and in any case the conversion would not happen inside the last.fm support plugin, but rather the covers framework itself.

I added a simple Gui, so you can select the cover size. But the label 'extralarge' is misleading, because it's just 300x300 pixel.

I hope the patch will be committed.

Honestly if the largest covers are just 300x300, we could just use that and not complicate it with an option, IMHO.

@Sasongko Actually you're right, but I wouldn't change it now.

But I detect an other bug already:
If the a cover isn't found the plugin shouldn't return a blank array. Instead the plugin should raise a NoCoverFoundException(), so that e.g. jamendo search the cover.

I did change the default to 'extralarge' before i committed.

I wrote a patch, which fix my previous patch and the cover manager. I removed the GUI because it's just useless.
I'm sorry for the inconvenience caused to you.
