Multiple scoring chains (Frontend)

[ma2bd]

Motivation

Update the frontend to finish the work after #39

Proposal

• Update the APP_ID and other constants to follow the new design
• Make the new app query the puzzles solved by the previous one
• Use 4 scoring chains

The description of the scoring chains and the mapping from user address is in the web app itself. This means we can change it later.

CAVEAT: By allowing several scoring chains that can change, we're making the tracking of scores in the portal more difficult in several ways.

• Old scoring chains must always be queried for some time because users may still use the old app.
• When we change the set of chains, reports of solved puzzles may become duplicated.

Test Plan

Manually tested with test user (old app then new app)
