Here's whatsnew:

Corrected sound in the tnzs driver
Correctly fixed coins in the wc90 driver
Enabled Tazmania in the megadrive driver (it works and I like it :) )
Added support to the FM core interfaces for sound mixing
Removed kaillera support. The client can be removed and probably should be due to being a potential security risk. Left netplay, chat, etc. code in the program so it has potential to be used with a different netplay system.
