Add activity log to all relevant objects, etc

• Stores should maintain a list of the transactions that happened: who bought/sold, what they bought/sold, the total price, when stuff gets sold out.
• Stores should track changes to prices and additions/removal of items for sale
• Tables should track everything crafted on them, the fees paid, when they were started and finished. Logs should update, so that theres one entry per crafted item that adjusts as it progresses.
• Same for Currency Exchange object, repair station, contract board, work parties, and any other relevant object.
• Logs should persist upon pickup/putdown (there are interfaces for this already)

Create a design doc for how this will work first and get it approved.

We have store logs up to 100 last transactions, maybe this list can be expanded on? but im worried about DB size bloating if everything is tracked. For example mishkas server has been running for 120 days almost now and his backup sizes are over 6gb each. This amount of data across 100's of players is 100.000 entries per day at least how will this effect DB's and overall performance?

To get some perspective to this. On an average public server ( not official that tend to amass more players ) You are looking at 30-100.000 items crafted per hour on average. Economy trades seems to float around 200-800 per hour depending on server economy collaboration( if people are playing more of a communion or if its a free market situation ).

When you have larger servers this is expanding quite rapidly with 100-300k items crafted and 1000-2000 items trades per hour.
