[chirp_devel] [PATCH 0 of 3] Settings arrays and UV5R ANI code

[Dan Smith]

When I wrote the RadioSettings stuff, I planned for values to be able
to be arrays. A RadioSetting can be composed of one or more RadioSettingValue
objects, but there was no example setting with which to demonstrate this
situation. The UV5R ANI code actually fits this rather nicely, in that
it is actually an array of integers.

This patch fixes a few bugs in the array support, makes the UI properly
handle array values by arranging the value widgets in a horizontal row,
and makes the UV5R driver expose the ANI code as an array value.
