Product transaction history and undo button.

[ssiegel]

Bellow the stock items, show the last few product transactions.
The transactions lines can probably be similar to the stock lines in appearance.
Each line should have a undo button at the far right edge.

Thank you, after testing I see the following issues:

• The list of transactions seems to have arbitrary order, with the most recent transactions all over the place. It would be good to have the most recent transactions at the top of the list.
• After undoing a transaction, the transaction disappears. It would be nice to keep it in the list struck out, like in Grocy itself.
• When undoing a transaction, an update of the product page should be triggered, so the new state is reflected on screen without unnecessary delay.
• The "Transaction" column should be left-aligned, the amount right-aligned.
• A "Location" column might be useful in general and for the transfer-from/-to transactions in particular.

Undoing a product-open transaction doesn't seem to work, at least if opening the product involved an automatic transfer to the consume location (i.e. the transaction consists of product-open, transfer_from, transfer_to). The selected line disappears from the list, but the transaction isn't actually reverted, the data on the product page doesn't change, and when viewing a different product and then returning to this product, the transaction line is there again.

This was merged, minus the last commit “correctly refresh remote data after consume” because it causes a regression (stock not updating immediately after consume).
