Unofficial fix for Redpower Screwdriver bug, plus additional tweaks

I've been seeing chatter over a new mod called rptweaks on the irc and forums, increasing the past week. It finally hit the Redpower unofficial wiki main page but I haven't seen it mentioned here yet so figured I'd give it a plug.

Nothing much to say other than I'm using it and it appears to do everything as advertised; makes the screw driver work with bus ids on computers again, gets rid of dropped items when breaking certain blocks in creative, and optionally adds a clear button to the Redpower project tables.

Your mileage may vary but I personally love it. Oh and for reference this is for Redpower 2 pr6.

Link to the wiki again for those skimming: Wiki

Hope this helps some folks until we can get official fixes for this stuff.
