Two new files. This is kind of ugly code, but I want to go ahead and make

* testgdate.c, testgdateparser.c: Two new files. This is kind of
ugly code, but I want to go ahead and make the tests available.
It isn't contaminating any other code. :-) Since one of these
is interactive and the other takes a while to run, I've kept
them separate from testglib for now.
* Makefile.am: Build gdate test programs.
