[IMP] hardware: Remove EAGLE board revision from VCS

[ADD] hardware: BlueBus v4 Board Changes * Remove BC127 LEDs * Enlarge all IC pads to make SMD assembly easier * Rewire 3.3v Rail into a star topology to do away with potential issues from dasiy chaining * Rewire portions of the 5V rail * Rewire MIC_IN Signals to make use of stereo audio * Tighten up similar signals for better board routing * Enlarge all vias to 0.51mm * Elarge 5v rail to 0.55mm * Tent all vias for a nicer silkscreen * Update silkscreen positioning * Remove wires from under TPA6013 since it contains a thermal pad

[ADD] hardware: Update Schematic and Board * Remove local libraries that can be found by EAGLE automatically * Rewire VIN side of the board * Update D4 to be a 30V 2A Diode, instead of a 100V 250mA diode

[IMP] hardware: Add Diode to 5V USB Input * Add diode to prevent voltage oopsies in case someone plugs > 5VDC to the rail

[IMP] hardware: Minor updates to design * Increase trace size to 0.22mm minimum * Increase all power traces to .5mm minimum * Add silkscreen goodies and name parts directly on PCB * Ensure all nets are named aptly

[IMP] hardware: Finalize Schematic & Rev 1 board * Finish Schematic * Finalize board layout for rev 1 board

[ADD] hardware: Create Schematic * Add major components to schematic and wire them

[REM] hardware: Remove existing files

[IMP] firmware: BC127 /BMBT Fixes * Alter UART RX ISR to perform quicker and thus not leave bytes in the RX buffer * Add Timer to write the BMBT Menu after a given timeout if it has not already been written * Send RadioMenu Disable message prior to writing the menu to prevent fighting with the radio

[IMP] firmware: BMBT / CD Changes * Rename "BlueBus" to "Bluetooth" * Move back button to 9th screen index on all screens, for consistency
