Web apps: transactions confirmation

[chapati]

Need to implement transaction confirmation popup in the same way as it is done in the web wallet. Need to handle all cases - multiple asset, deposit/withdraw, fee-only transactions &c.

UI files from desktop attached for the reference. Start from applications.qml onApproveSend/onApproveContractInfo confirm-desktop.zip

Couldn't find the design, but the fields should be aligned somehow

let's reopen confirmation each time when user calls a new confirmation

For example:

1. user opened deposit confirmation on DAO and try to open a deposit confirmation on Faucet
2. user opened deposit confirmation on DAO and try to open withdrawal confirmation on DAO etc.
