Pending inbound direct transactions not shown

[karalabe]

This seemed strange to me because we already support this feature in EtherAPIs and it's a very nice and very simple thing: seeing currently pending inbound transactions (plain ones), or pending balance changes.

It's very easy to see whether there's something coming inbound since we can query the current balance and the currently pending balance, which gives an awesome overview that someone's sending us funds.

This an be further extended that whenever we detect a balance change, we list the pending transactions and match up any of them with our own accounts. This allows us to list inbound transactions while they are pending.

E.g. a screenshot from etherapis with this working:
