Load transaction history from other clients

[danfinlay]

Right now we only log outgoing transactions from the same instance of MetaMask.

Long term we should load all transactions from that account, so even if someone has multiple metamask instances, they both appear "up to date".

Related to #133 but kindof is the inverse of it.

I recently encountered problems of unknown origin that caused my Metamask to be suddenly very-very slow, high CPU using, and often getting completely stuck. Problem similar to #4012, #2754, #6817, etc. After Metamask reinstall, it works fine.

But now I lost the history of all transactions, which is not good, but ok. The real problem I got now is my still pending transaction with quite low gas. Since Metamask doesn't download history, I have no way to increase the gas price for that pending transaction in the wallet.

Since #133 is already solved for some time, can this issue be resolved as well? Or at least be put to some upcoming milestone?

@PatrykLucka did some work towards showing external transactions instead of only Incoming transactions, unfortunately a lot more background work is needed to make this possible. Namely we need to be able to deduplicate transactions and a new way of grouping them by intent versus by nonce. #10908 represents a good effort to bring external transactions in and could prove to be useful to future efforts to land this feature.
