Rebrand Proposals table

[peterjurco]

Closes #461

What does this change?

• Restyles the proposals table used in Governance & History page according the new designs (History page is not yet done)
• Adds logic for ✅❌icons in the vote bar - previously it was one set of icons, now we have two sets. See slack discussion
• Refactors <Tag> element a bit so the styles can be done inside the component based on the type ("primary" or "secondary")
• Adds some temporary testing capabilities so we don't need to manually play with proposals locally to get them in the desired state (I will remove it before merge)

How to test it

• Go to the src/pages/proposals/proposals.tsx
  • uncomment lines 50 -72
  • comment out line 76 (const sortedProposals = openProposalsSelector(proposals);)
• Go to the src/pages/proposals/test-proposals.json and change data to desired state. Most important fields:
  • type can be "primary" or "secondary"
  • voterState can be 0 (Unvoted), 1 (Voted for), 2 (Voted against)
  • open, executed,
  • yea, nay - votes distribution

I will remove the test code in #502
