@bjonkman of Envision Energy recently reported to me that she found a minor bug in the FAST driver/glue code that results in incorrect values of the generator torque and electrical power being sent from ServoDyn to Bladed-style DLLs. There has also been some discussion about this on the forum: https://wind.nrel.gov/forum/wind/viewtopic.php?f=4&t=1668&p=9779. Bonnie said she'll provide NREL with the fix soon.

This fixes issue with DLL controller getting constant values for GenTrq and ElecPwr, as reported in OpenFAST#40. 

If SrvD%y is ever used in another way (e.g., linearization), this method will have to be fixed. Note that it breaks the framework--but the Bladed DLL breaks the framework, too.
