New voting tab for proxies?

**Is your feature request related to a problem? Please describe.**
Proxies play an important role in Bitshares. Often users do not have time to analyze every single proposal and instead may opt to proxy their voting power to someone else who they believe can represent their interests in voting. The problem is knowing who these people are is difficult and there is no single location to get this information, its often a case of trying to browse the forums or asking random people on telegram. Knowing what proxies vote for easily is another issue.

**Describe the solution you'd like**
Another tab in 'Voting' in the UI where a user can see a list of proxies by voting weight. It would also be good to take this opportunity to perhaps list additional fields like a link to the proxies voting forum thread or communication area.

**Describe alternatives you've considered**

**Additional context**

Start at the existing Voting tab in the JavaScript/React UI and trace how voting information and weights are loaded. Define the proxy list data and links from the issue requirements, then verify that the new tab presents proxies ordered by voting weight and includes the agreed communication links.
