fst['ServoFile'] assigned incorrect value in fast_input_deck.py #74

FASTInputDeck.write() assigns filename_AD to the fst['ServoFile'] entry in line 444 of fast_input_deck.py.

This is surely a typo, shouldn't the offending line read fst['ServoFile'] = '"' + os.path.basename(filename_SvD) + '"' instead?

Otherwise, the main fst file generated ends up with an incorrectly defined ServoFile file entry, e.g.:

...
"<basename>_AD.dat"   AeroFile    - Name of file containing aerodynamic input parameters (quoted string)
"<basename>_AD.dat"   ServoFile   - Name of file containing control and electrical-drive input parameters (quoted string)
...
