added more tests to check for id's and por-id's and use them when necessary
Added tests regarding ordering of the children when creating a POR repo object in-memory. Since writing of the files is based off of this, we should be good; just as well, we probably don't want to write to files and then make sure the output is correct, as that is basically an integration test
Tests added, examples of what parse5 fixes added
