Create pending tx component

[okwme]

This component can store all created transactions as hashes in local storage. These transactions can be queried for their status and showin in a popin panel where they're at. Even if the user refreshed the page they'd know what the status of their different transactions were. This would be great because when you submit a claim it just site there, so now you can navigate away. We could also attach the resulting behavior to the tx component instead of the instance event. This would help to handle user action flow if they've navigated away from the view but you still want to add an action more than a notification. It would also make it possible to give them a notification even if they'd refreshed the page, restarted the tx with more gas from their wallet.

• add peding txs to store
• add pending tx store to local storage
• add query to check staus
• add compoentn to list transactions and list status and remove tx from watch
• add action to be executed upon success and upon

maybe instead of local storage they're actually kept by the user profile on the database
we could keep a record of dapp related actions from the user that way if they wanted to review them....
