Update for dex 0.6.3 (#1142)

* dcrdex release 0.6.3

- Change download link to read "Download" instead of "GitHub"
- Add news item
- Update download link to 0.6.3
- Revert release note link to 0.6.0. This is a more far more detailed
  document than the patch release note (which links back to the 0.6.0
  note anyway)
- Add link to dex.decred.org

* wallets: Highlight links on hover.

Change color slightly so its easier to see which link you are hovering
over.
