Ore box verbs

Removed attack_hand proc that would open a browser window to view the contents of an ore box.
Integrated it into the examine verb, and added an empty ore box verb for emptying it.
Restricted usage of checking contents and emptying it to only if you are standing next to the box as you would have to physically open the box to check the contents.
The for loop that tallies the box contents is restricted to only run once per second to prevent server spam.

Rewritten based on feedback from the last PR, and targeted dev because *phoron*
