Fixed finalising of tolerance in gmres solver
Updated test data to be inline with fixed hopping kernel and bicgstab inverter
Merge branch 'master' of ssh://orentago.linkpc.net:535/pyQCD

Merging fixed test data
Removed gmres and bicgstab propagator test data

The invert_*_dirac tests will already test the different solver methods,
so it seems pointless to triple the storage of test propagators in this
case.
Removed some defunct test propagators

These are cases where more than one type of smearing is applied at any
one time. This seems pointless as each type of smearing should be tested
in isolation, and then only once. Besides, the test doesn't use them
anymore anyway.
