[theora] Theora player for Nokia Series 60

[Stuart Fisher]

I've now uploaded Alpha 21 here:

I've changed the compiler options so this version should now work on phones 
without floating point hardware. Nik could you please try this out on your 
E71. Hopefully it will work now. Thanks.
I've also changed the scaling logic to disable scaling if the video is 
larger than the screen.
