Added the first of many unit tests. For now the unit tests are just built with

everything else in the all target of the makefile, which is fine, but relies on
CppTest, which can be found at http://cpptest.sf.net

Also fixed some things I've been meaning to get to for a while in the xml
system, including a few bugs that will make coping with malformed data not hang
other programs, and do the error reporting in a nice way.
