Subject: Adds osDrawPolygon to OSSL. Works a little different then other OS
 Drawing functions, this one has no start and end point, but a number of
 points that will form the desired polygon. Only FilledPolygon implemented so
 far. * Also added some LSL transparent type conversion, as it's done in LSL
 scripting (string to integer, float to string, etc)
