Fixed the graphics whiteout bug I introduced when switching profiles. When Refresh() was being called on the texture, the bitmap wasn't been re-transferred back into the openGL context.

While debugging this, I noticed a separate issue:  when changing profiles, we'd actually call refresh twice.  Removed the spurious call, as reloading profiles doesn't need to concern itself with the image cache - that's already covered by the game options menu.

Also did some minor formatting / cleanup in the JGfx code for PSP - stubbed out a bunch of JLOG calls I had put in while debugging the PNG loading code.
