Querying a Edit Box (Integer)
GUI_QIIBOX! VAL%, min%, max%, x1%, y1%, x2%
If the edit box from (x1,y1) to (x2,y1+10) was touched, this function draws a dialogue that allows the user to modify the value. If the value is smaller than min or greater than max, it is bounded.
If the value was changed, the function returns true, false otherwise.
