Change SOURCE_DUSTCAP to SOURCE_FLATCAP and SOURCE_DARKCAP in Ekos capture
Review Request #128718 - Created Aug. 19, 2016 and submitted
In calibration for bias - dark and flatfield image capture in Ekos, only Dust Cover with buildt in flat field source is supported.
Changed the existing SOURCE_DUSTCAP to SOURCE_FLATCAP and added SOURCE_DARKCAP.
Dark cap will park and turn off light source when taking bias and dark frames, and unpark plus turn on light source when taking flat frames.
Used with parkMOunt and flat light source in mount park position
Tested with custom driver ServoBlaster Cap https://github.com/magnue/indi_servoblaster_cap in KStars + Ekos on ubuntu 16.04 LTS
