Include P&L posting for expenses and non-stocked items into WIP ("change in WIP")

For stocked items, the system is posting the "complete" transaction:

1. Project cost (debit) - Inventory (credit)
2. WIP (debit) - Project cost item (credit)

Project posting for expenses and non-stocked items is just

• WIP (debit) - Vendor, or any other offset account (credit)

However, according to total-cost account method, this is incomplete.

The GL entries must be:

1. Project cost (debit) - Vendor, or any other offset account (credit)
2. WIP (debit) - Change in inventory (credit)

Therefore,

1. rename "Project cost - item" to "Change in WIP"
2. apply not only to stocked items but also to expenses and non-stocked items

In project expense journal and expense management reports,

1. if the project applies WIP (Balance sheet), add "cost" and "change in WIP" posting types,
2. if the posting does not apply WIP, just post project cost.
