FixtureResource never gets remade

[James Westby]

FixtureResource overrides isDirty to state that it is always dirty.

However, when the support code sees that, it will trigger a call to reset()

The default code for reset only does a reset if self._dirty is true.

This means that despite always being dirty the resource is never cleaned.

+ def _get_dirty(self):
+ return True
+
+ def _set_dirty(self, new_val):
+ pass
+
+ _dirty = property(_get_dirty, _set_dirty)

Causes the fixture to always be reset.

Thanks,

James
