Create "appendix" type lists that show values people can query for

[mhkeller]

For instance, in t2, a reporter asked me for all of the programs that could be making deposits or withdrawals. The queries for this are pretty simple:

SELECT DISTINCT item, type FROM t2 where type = 'deposit'

but if you don't know sql...

I suggest we add something to the wiki that gives a record of the values in these tables so people can get a better sense of what's in them.

I think this is the same as issue #98.

They are separate issues.

Issue #98 is about documenting the detail of table 2 which is that you should be aware that both deposits and withdrawals exist in that table and if you want to know how much money X cost, you need to use the net value.

This issue pertains to showing what the relevant items are query-able for all tables.

@cezary4 agrees that this issue should be added. He's working on this and it will be added to the wiki as a third item called "Field definitions."
