VampireAE fixes, mmm'kay

Several fixes here.

1) fixed if internal player has suspended AE and supports volume changes
2) really suspend/resume alsa
3) sleep a little in CSoftAE::ProcessSuspend so we don't suck the life out of devices
4) suspend/resume AE when we actually suspend/resume, d'uh.

This is an attempt to resolve the linux suspend/resume Frodo Blocker.
