Fix some of the issues with bank handling (#461)

Browse Source 
* Fix for Issue #457 - changed m_nNumLoadedBanks to be m_nNumHighestBank and updated functionality in menus accordingly.

* Fix for Issue #460 implements MIDI Bank Select MSB/LSB based on PR #395 submitted by @abscisys

* Fix for Issue #458 to not show blank banks in the menus.  Also handles MIDI bank select messages and won't change banks if the final selected bank isn't loaded.

* Firm up bank validity handling slightly.
