[Done for V0.39] Default clicking actions

[George Gilbert]

FYI, I've added 8 additional "converts" to wallitem, flooritem and monster objects, each of which are checked whenever the mouse is clicked on an item of that type when they're on the tile infront.

For example, the function of a fountain can now be duplicated by anything (e.g. a monster that fills up your flasks etc) as follows:

- set click1 to do an action of swap mouse flask_empty to flask_water
- set click2 to do an action of swap mouse waterskin_empty to waterskin_full.
- etc

(i.e. all of the actions will be performed, but in the above example, only one - or possibly none - will actually do anything).

Equally, you could create a statue that when clicked converted to a monster, or a monster that when clicked initiates an NPC conversation, or...you get the idea.
