Add cancel, complete, issue, ship, to SO/PO/BO

[miggland]

As discussed in #90, this PR adds support for the following:

• [X] Cancel build order
• [x] Complete build order
• [X] Cancel purchase order
• [X] Complete purchase order
• [X] Issue purchase order
• [X] Cancel sales order
• [X] Complete sales order
• [X] Ship sales order

Will be draft until tests are added for the first two incomplete points..

The Complete build order state test is blocked by #3515

@miggland thanks for this, I think the implementation is nice and clean, and I like the solution of "aliasing" functions
