Andrew Tridgell f6d7d1bc59 APM: changed PID library to do automatic deltat calculation 
this fixes a problem with the HDNG2RLL PID, which was using the wrong
time base and prevents similar bugs from happening in the future

jasonshort 4ec8805216 Reverted to older PID. Restored the older filter, and removed PI command. I am no longer using PID for the quad and have switched to PIPI loops which perform much better. The D term in this class is not that great.

tridge60@gmail.com 5c68a04c5d PID: fixed an uninitialised variable 
we did not initialise derivative to zero

jasonshort 915a564b8f Changed the PID derivative filter to a moving average with 4 samples. Having great luck with it and High kD when using noisy sensors.

jasonshort 5a22080484 I am Adding A "PI" loop to the mix. This is a need for AC2. We can optimize the internals later, but I basically duped the get_PID and removed the D term internals.
