Finish Release-2.7.2-X
Modified conan to allow for unchecked arguments to be passed to the process command line.  Incremented minor revision.
Modified interface to and AbstractProcessParams, so that a ProcessParams object can create apache command line options automatically.  Also can do much of the parsing automatically as well.  The interface change is mainly in the AbstractProcessParams class.  Now this class handles the parse method, but now requires subclasses to implement a parseCommandLine method.
Fixed a bug when parsing command lines.  If command line is null then method failed.
Small modification to reduce spam when logging.
