Readme Fixes - Githubissues

The readme is pretty much up to date now.

There are some links that still point to https://code.google.com/p/a2dpvolume/. I am not sure where the binaries are going to be on under GitHub.
The link to Previous versions still points to https://code.google.com/p/a2dpvolume/.
Is "Known issue with older Samsung Galaxy S phones not capturing location" really true anymore? The issue seems closed, but the warning remains.
The browse source link still points to Google Code. I don't think that this area makes much sense in GitHub: It needs a more extensive rewrite.
