Blinkm fix

Fixed state detect logic. Added two new state indicators:  Flashing orange safety off, and flashing blue failsafe. Changed safety on state to solid cyan (was red). Increased LiPo cellcount support to 6.  Tweaked RGB value to create better distinction between Orange, Amber, and Yellow.

For some reason this pull request picked up Lorenz' latest px4io uploaded edit (I only show the blinkm.cpp edited in my area).
