New package runners for Runner classes. At the moment only contains the new class NaccessRunner (moved out of Pdb class)
Introduced a config file for tests so that one can set externally the executable paths and any other necessary data to run tests (at the moment only implemented in PdbTest.java). PdbTest now should run anywhere (if you have a local pdbase installation!)
Moved the consurf parser out of Pdb to its own class ConsurfConnection in the connection package.
