Lock height of pillars / beams

With the current (and amazing!) "Fun with objects Part 1" pillars are stretching to meet the ceiling if you have multiple levels and the ceiling is higher that just one floor. It would be nice to have some kind of "lock" for this feature, so we could manipulate the pillars size inside rooms.

Proposed changes:

• Always cap the height of an "unlocked" pillar on the ceiling it's under, allowing the user to raise it's thickness only when raising it's size. Useful for higher ceilings to have monumental pillars.
• lock the pillar in its height at the moment, allowing the user to move the pillar into different rooms mantaining the same height (for other creative uses of the asset) and manipulate its size freely, without the cap of the ceiling.
