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

Changes for Build #129
[Dan Smith <dsmith at danplanet.com>] [uv5r] Allow backlight setting to be 0-10 for newer radios

Note that this may also allow the setting to be forced higher for the
older radios (feedback encouraged).

Fixes #366

[Dan Smith <dsmith at danplanet.com>] Make the upload process report an error to the user

This should have been done long ago, but was needed to properly display
the firmware incompatibility message to the user in support of the fix
for #344.

[Dan Smith <dsmith at danplanet.com>] [uv5r] Read the auxiliary block before uploading to verify firmware compat

Thanks to investigation by Jim Unroe, it looks like the version stored
in the aux block is non-volatile and reliable for version detection.
This change checks that block against that of the image to make sure
that there is an exact match and refuses to upload if not. This could
potentially be made more tolerant by allowing the upload, but skipping
the aux block for non-firmware matching radios.

Addresses #344

[Dan Smith <dsmith at danplanet.com>] [uv5r] Fix reference to missing variable in clone error message
Fixes #368
