Better readability of transaction signing dialog

I think readability of the transaction signing confirmation is a matter of security. Some minor formatting modifications like below would improve readability, and therefore security.

### Transfer Request
____________________________
App: **Transfer Example** from **examples.get-beet.io** wants to **initiate a transfer** from **BTS:myaccount**.:

```
Action: Transfer
Recipient: clockwork
Amount: 0.00100000 BTS
```

No file, test, or entry point is named in the issue. Start by locating the transaction signing confirmation dialog in the JavaScript application and compare its presentation with the proposed Transfer Request example; done means the confirmation is more readable while still showing the relevant transfer details clearly.
