Partial fix for #241
- Move to next loading place when the current one is partially blocked (see #241)
- Fixed issue related to #43 where the next pallet would load too far away if it didn't fit in the first space attempted
- Reduced boundary when measuring testLocationIsFull
- Reattempt to measure pallet size multiple times, as it appears to fail for reasons other than object.updateLoopIndex == 0
- Rearranged some pallet debugging prints to only show sizes when the pallet is valid
