    Fix static code checker warnings about parameter definition in doxygen comments
    
    Apparently these shouldn't suffixed with a colon (:)

commit d1ff16138eec2dc388cb90c5d9da51af2d2fd44f
Author: Geert Janssens <geert at kobaltwit.be>

    Add GncDateTime constructor taking a GncDate as parameter
    
    As a GncDate doesn't have any time information, this has to be made up.
    GnuCash uses 3 times-of-day quite a lot:
    - start-of-day (00:00 local time)
    - end-of-day (23:59 local time)
    - neutral time (10:59 utc, chosen to minimize
      day offsetting when converting to/from localtime)
    
    A second parameter to the new constructor will tell it to use one of these presets.
