Update from Arnova8G2:

- Final V6 will support more than 20 devices.
- So far Arnova posted 15 v6 betas, but because changes are small or device specific I "ignored" all apks since beta 3.
- This is the latest beta (v6-beta15) and includes all changes since v6-beta3.
- If you're using v6-beta3, upgrade to this version as it fixes many bugs.
