[chirp_users] New Daily Build

[Build System]

Greetings,

A new daily build of CHIRP is available.  This includes changes made
directly to the tree yesterday, and may include additional features,
bug fixes, and/or bugs.  If you are interested in trying it, grab it

A list of the changes included in this build (since the last daily)
follows:

Changes for Build #399
[Tom Hayward <tom at tomh.us>] [AP510] Disable AP510 driver. In response to #3617

Only a buggy, outdated firmware version is supported by Chirp. Newer firmware
revisions changed the programming protocol and are incompatible. To avoid
confusion and discourage running buggy firmware, this patch disables the AP510
driver in Chirp.

The code should remain, as it is a great starting point for anyone wishing to
write support for the latest AP510 firmware.

[Tom Hayward <tom at tomh.us>] [IC-T8A] Fix frequency encoding and decoding. Fixes #577

The IC-T8 stores frequencies in three bcd bytes. The last nibble of these three
bytes would naturally be the least significant digit in KHz, but this leaves no
way to encode frequencies divisible by 2.5 KHz. To account for this, the IC-T8
deviates from its standard bcd encoding for the final nibble. Instead of the
nibble representing 1 KHz, it represents 500 Hz: 0x5 is 2.5 KHz, 0xA is 5 KHz,
and so on. This patch implements this encoding and decoding in Chirp.
