[chirp_devel] [Bug 821] Add VX8 memory layout in preparation for APRS settings menu

Hi,

This patch adds the APRS menu settings to the memory description for the VX8 series of radios. I intend on adding an APRS entry to the Settings tab, enabling users to alter the settings.

I've successfully checked the attached layout against memory images for: VX8-DR VX8-DE VX8-GE I've attached an image of my VX8-DR to http://chirp.danplanet.com/issues/821for addition to the tests/images directory.

The settings memory layout doesn't exactly match the VX-R in chirp/tests/images/, and since I don't have VX8-R to examine I won't enable the settings menu for that model. The APRS beacons memories for that model parse OK.
