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

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.
