Restrict blue candle usage

[facerix]

• Limit the blue candle to a single use per screen

[facerix]

much easier than I expected:

in loc.Candle:

• add a 'available' boolean property
• modify getProjectile(): function(args) { if (this.available || this.color) { this.available = false; soundManager.play('candle'); return new loc.FlameProj(args); } }
• add a new function, reset: function candle_reset() { this.available = true; }

add this line to loc.Player.updateInventory(), under a new 'loc.Candle' clause: dojo.connect(game, 'setupMapScreen', game.player.inventory[3].reset);

That should do it.

made a few minor tweaks based on runtime testing of this solution. seems to work.
