Workflows for transactions

[ehuelsmann]

We need workflows for all rows in the transactions table. A number of tables reference transactions.id, specializing rows. This ticket tracks progress.

We have workflows for:

• AR
• AP
• GL, which is itself specialized by
  • (unspecialized)
  • asset_report
  • inventory_report
  • payment (for overpayments)
  • yearend

The following tables refer to transactions.id, but don't specialize the transaction:

• file_transaction
• invoice
• recurring
• status
• voucher

The file_order_to_tx refers to gl.id but doesn't specialize the GL transaction.
