Create Fee wizard in Preferences

[jim618]

Fees tab
Miners' fee
The current miners' fee is 1,000 satoshis per kB.

You can increase this fee which might get your transaction into a block faster
Slider 1,000 to 10,000 with intervals of 1,000 satoshis.

Client fee
The current client fee is 1,000 satoshis per transaction sent.
You currently owe XXX. Payable in Y sends.

• Ability to overpay BRIT if you like to avoid privacy issues.

Add the MultiBit donation address always to the list of BRIT addresses.
Add a panel to the Fee Preferences screen/ wizard making it easy for users to donate, explaining fees up to the donation amount are waived

This is working but still needs some code refactoring and FEST tests.

Looking good! Will need the supporting text to explain the effect of moving the slider around and a summary of the client fees.

Updated screenshot with more explanatory help and a donate button (that fills out the Send screen directly for the user):

Looking good. Some UI suggestions:

• include the outstanding client fee balance and when it comes due (replicate the Send confirmation panel info) since this is essentially a dashboard view
• Change "Default" to 1000sat since we know that is sensible (perhaps start from 500sat?)
• Consider making the "Donate now" button an actual Wizard button so it appears on the bottom row next to Apply - it would be more pleasing to the eye and may be more likely to get a "curiosity" click.
• The "Donate now" button could also have reduced text "Donate" and probably won't need an ellipsis since users will expect the chance to cancel out of the send process.

I've finished off this issue with:

• some layout tweaks
• refactored out a Sliders factory class
• two FEST tests to check the slider and the donate button

Ready for review and closing

Verified working. I think we need a discussion about the default values since 3000sat seems too high to me. However that discussion is not a blocker for the issue so closing.

RE: the default - I suggest we try it out in real life during Beta 7 and set it accordingly.

It may well change from release to release as the fee structure changes.
The lower and upper limits may well change too.

I have put in a 'normaliser' so that the value used is always between the lower and upper limits so we can tweak the value going forward as the fee structure for Bitcoin transactions changes.
