Steps to Reproduce

Rez an object, open the Object Profile floater on said object, set for sale, set price to L$0, observe the price increased to L$1.

Actual Behavior

Attempting to set an object for sale for L$0 from the Object Profile floater forces a minimum price of L$1.

Expected Behavior

The price should be left at L$0 as it is when setting from the tools floater. A comment in floater_tools.xml states this is the intended behavior:

<!-- NEW PRICE SPINNER
Objects are allowed to be for sale for L$0 to invoke buy UI behavior
even though the user gets a free copy.
-->
