[IMP] firmware: Upgrade To Melody 7.2 * Account for lack of full metadata broadcasts from the BC127 by broadcasting the update event after a given timeout * Move metadata and playback status out of the connected device struct, since we can only ever have one connected device * Minor updates to the way we set the connectability/discoverability of the module

[IMP] firmware: IBus / BM53/54 Improvements * Resolve issue with Glitchy Menus * Remove useless screen refreshes so that we can move away from the timer based menu writing system

[IMP] firmware: IBus / BM53/54 Improvements * Move Menu Writing to a scheduled task to avoid glitchy menus * Report 1 disc loaded to ensure that the radio does not fade out momentarily while switching menus * Only write out Area 0 when "No Disc" is reported * Lower IBus TX delay to 10ms, since that is sensible

[IMP] firmware: BM53/54 Improvements * Add menu enable / disable message * Correctly report number of discs in changer to get rid of "No Disc" error * Move UI elements around so they make more sense * Improvements to BT device handing

[IMP] firmware: Add SFR setters and move task execution * Remove all manual calls to SFRs in favor of the SFR setters * Move task execution to main loop instead of the timer interrupt * Use Timer1 instead of Timer3

[IMP] firmware: Update Gitignore

[IMP] firmware: Remove private Makefiles

[IMP] firmware: Add EEPROM support & Abstract some code * Add EEPROM handler for 25LC256 SPI EEPROM * Abstract the RPOR Mapping code into a function that can be called anywhere

[IMP] firmware: BC127 Playing and BMBT Menu improvements * Use A2DP streaming status to update playback state * Attempt to reconnect on error even if no device is active * Write entire menus back out on BMBT screen clear

[IMP] firmware: Improve IBus BMBT functionality * Document a little better * Update paired devices on the BMBT Menu
