Custom mode values are not listed in the documentation

[patrickelectric]

It's not possible to know the custom mode values described here: https://github.com/ArduPilot/ardupilot/blob/master/ArduSub/defines.h#L33
besides looking into the code.

This is important for mavlink messages that need such values to change mode

[patrickelectric]

The page already contains the modes http://www.ardusub.com/reference/ardusub/features-while-in-operation.html, just missing the values for each custom mode

@patrickelectric are you wanting the brief descriptions added to the "Flight Modes" docs, or are you also thinking the enumeration numbers should be included?
