Server1 tomato plants die before producing

[Quasic]

In working branch:

The perl scripts prefixed by g- control tomato plant growth. They are called by refresh.pl. They basically change the item into another item if conditions are met. Conditions may include the tile the item is sitting on, and randomness. One of multiple replacement items may be chosen randomly. New items may also appear on adjacent tiles if they don't already have items.

When implementing this in server1.js, I created xform() to handle the transformation. Tomatoes in server1 are currently untested and I haven't yet implemented g-Ia.pl, which causes the plants to make tomatoes. I believe this is the last perl to js conversion needed for server1 to fully implement DB.

Times may also be too long for a single-player game.
