Updates to test_ocr_clock.lua and fishing.lua ...

test_ocr_clock.lua - Adding missing srReadScreen(); Prevented clock from displaying if clock was previously not found (ie alt-tabbed out of game for a moment.)
fishing.lua:
Updates to sound effects, timers, etc. New sounds added, old sounds updated with new files (different volumes, clipped, etc)
Also there are now two fish caught sounds now (cheer.wav and applause.wav). Cheer.wav is low sounding, blah type of cher when you catch common fish.
applause.wav is more enthusiastic cheering/clapping/wooting sound that plays when not common fish are caught.
Multiple bug fixes
