Fix Bug with term.setCursorPos

Browse Source 
I fixed 2 Bugs:
1. If you call this function, without 2 numbers, you get a error in the window API and not in your Program
2. If you call, this function with 2 numbers lower then 1 (e.g. term.setCursorPos(0,0) ), CraftOS will hang forever and need to press Ctrl+R or rejoin the world.
