Add post-build events to copy DLLs

Three DLL files (bass.dll, bass_fx.dll, and OptimFrog.dll) need to be located in the same folder as the assembly when running.
Add migration of equalizer profiles

The new equalizer uses ten bands as opposed to eight in the old one. This causes a crash when a new player runs with an old configuration.

Unfortunately this migration was missed in the last upgrade, which is why it is very important that those users get this migration.
