Feature: Add ability to vote in the Governance tab directly from the GUI

[kxcd]

This is a low priority feature request for the v0.19 or v0.20 of the qt wallet.

The request is to extend the UI to allow voting on proposals with the vote-many option either from the main grid directly OR via the details pop-up when you double click on the proposal.

Option 1: Vote from the grid.

A new column is introduced to the UI with three coloured solid circles. Say Green, Red, Amber. By default they are displayed deeply faded, or perhaps even greyed out. Hovering the pointer over them should show the text Vote many Yes for the left most one, and Vote many No for the middle one and Vote many Abstain for the right most one. Clicking a button shall change the colour to bright green eg in the case of the left one, or bright red in the case of the middle one or bright Amber in the case of the right most one indicating a vote has been cast. When the tab is first opened, the UI should poll the network and display any pre-exsting votes as appropriate.

Option 2: Vote in the details popup.

Currently when a user double clicks a proposal a dialog box is opened with a singular button on the right labelled OK. This solution would add a further three buttons to the left of it grouped by a border with a label Vote to the far left of the trio. The buttons shall be Labelled Yes, No, Abstain. Upon clicking the button a vote-many vote is cast, ideally with a OK popup and when the dialog box is closed a new column to the right of the existing proposals grid displays the vote cast, eg Y, N, ,A for each proposal, otherwise blank if no vote is cast. That column could be labelled something like Vote or Your vote, or My vote...
