Optionally display item IDs in all relevant reports

[N3Roaster]

There's been a feature request to display the item number in the Current Inventory and Availability Projection report. This is a trivial change to the SQL (line 85, concatenate the id in the first column of the SELECT statement), but it seems to me that this should be a broader request: allowing a person to toggle the display of these id numbers (on or off) everywhere.

If there's broad support (or nobody being particularly opposed to it) for just doing the trivial change, I'm not opposed to making that change before doing the broader work of making it a selectable option.
