Only test either the atomic or the simple version through the test
class, and have the type to test as a template argument.
Also added test source list file, which had been modified but forgotten
in previous commits.
* Makefile changes allowing for cross-compilation
* SRDData: had to rename an enum member from ERROR to ERR because
apparently creating a macro called ERROR is a thing in the windows
headers
* DynLib: ported
* Strings: fixes in toOSString, untested for now
* Fixes in some tests
* TODO list update

to visit all the nodes. Also added a method to create a "root node"
handle for the visitor, because I'm a lazy bastard.
