put command can crash driver

[irmen]

the put command allows for creating instructions that crash the driver because of an assert in the code that is violated.

For instance 'put me in table' will crash the driver because eventually a call to Player.insert is done where the item is the player itself.

• this should not crash the driver loop but rather log the crash, and continue afterwards
• the put command should be fixed to validate for cases that make no sense (and so avoid the assert error altogether)

[irmen]

Exceptions are now printed out but no longer crash the driver loop.

Still have to fix the put command where the player attempts to place a living inside something else (this causes the assert)
