SEQ64 V2.1.3

Added FL Studio compatibility mode. FL Studio does not support many types of standard MIDI commands, including SysEx and text events, which are required for some SEQ64 features. This compatibility mode maps these features to CCs instead. For more information, click the ? button next to the FL Studio compat checkbox in the GUI. This option is of course also supported via command-line.

Added CC map viewer (showing what all the CCs do according to all the commands defined in the ABI). Click the ? button next to the CC field in the ABI editor to see the current CC map.
