fixed null selection crashes with flexpath.
Removed the capability to have multiple aliases for the same transform plugin for now. This greatly simplifies some code, especially the plugin detection code, and by doing so fixes a compilation error on BlueGene
Merge branch 'xml-aliases-fix'

This fix removes multiple aliases for transform plugins in the XML. This simplifies the code, and fixes a compilation issue on BlueGene.
Fixed a bug in the transforms_specparse.c test that was causing non-deterministic failures on some systems (only the test itself was broken, not the feature it was testing).
Merge branch 'specparse-test-fix'
