[IMP] bootloader: Minor updates * Rename SN defines to include address in verbiage * Do not pull I-Bus TX pin to output mode and leave it as an input

[IMP] hardware: V 1.2 * Power PAM8406 PVDDR and add bypass caps * Rework layout for PAM8406 and its passives * Connect floating VIAs to ground

[IMP] application: Version 1.1.14 * Shutdown all unused I/O ports * Rename IO Port defines so they are consistent * Ignore values for coolant temperature that are outside of usual ranges * Resolve issue with radio overlay button in BMBT UI causing the UI to jump back to overlay mode even when on OBC / Nav * Add support for extended ASCII characters, since most BMW UIs support this encoding * Resolve issue with BlueBus keeping vehicles awake via TEL ON by shutting it down when the ignition is turned off * Resolve issue with BlueBus waking other modules up by pulling the I-Bus low just prior to sleep

[IMP] bootloader: Bootloader improvements for v1.4 * Turn UART pins to inputs when destroying the UART * Add additoinal NOPs to allow for consistent responses before leaving bootloader mode

[IMP] bootloader: Bootloader improvements for v1.4 * Shutdown unused ports * Correctly manage the BC127 PIO pin

[IMP] hardware: V 1.1 * Reroute 3.3v rail under the PIC24 to prevent ground returns on the second layer from having to take a longer route * Bring 5v rail to top layer for a short run in order to open the ground return path (to the left of the PIC24) * Leave pin 3 of the SPKR_OUT connector floating to prevent audio channel grounding on certain models * Add space between the edge of the analog audio ground plane end and the R/L channel traces * VIA stitch layers around the ground "bridge" (right above the BlueBus name on the Silkscreen) * Increase GND bridge to 1mm from 0.75mm * Increase BC127 pad size to allow more paste to fill the castellations * Bring RC filter for BC127 closer to power pin

[IMP] application: Version 1.1.11 * Call volume does not cause music volume to go sky-high anymore * Call volume is adjusted as the user adjusts the volume regularly so that the same audio level can be consistently achieved. * BM24 users (EU) should now not have problems with the radio becoming unresponsive when using the unit with the BlueBus * UI identification has been improved to prevent issues with the MKIII Nav units using the "older" (pre-version 40) UI * Mini Cooper R53 users with Navigation can now summon the BlueBus menu using the "RND" button on the CD53. * Coolant temperature can now be added to the Navigation headers (Settings > UI > Temps)

[IMP] application: Firmware 1.1.10 * Allow ignition status to be always on * Shift UI configuration options by one byte

[IMP] application: Firmware 1.1.9 * Add Ability to set comfort features via CLI * Add ability to control call volume via volume knob * Fix issues with static layout writing long strings missing a character * Add option to enable microphone pre-amp via CLI for aftermarket microphones * Remove code to set phone HFP volume via steering controls * Fix multiple TEL status broadcasts to I-Bus

[IMP] bootloader: Only write SN/Build Date when values are clear (0xFF)
