2.0 branch update

[rengels]

Hi all,

I haven't been sitting around doing nothing.

Currently I have updated the interface as previously mentioned.
You can now set and query information via asString(type) or setValue(type, 
value)
This should be more flexible for the future as you can add new meta information 
without breaking binary compatibility.

I've also update the examples and tests. Everything seems to be working right 
now except that I haven't implemented all the new information for every tag.
I will start doing this for id3v2 next week.

If you want to have a look at my changes I put the diff on my homepage here:

I hope we will decide on a solution for revision control soon.

Please keep tuned...

BR,
Ralf
