[encointer] introduce democracy and community treasuries

[brenzi]

Over the past few months, Encointer has developed a democracy pallet with one-person-one-vote governance for local communities. We think we're ready to experiment with our real communities on mainnet.

The governance scope of local democracy is restricted to

• properties of the local community itself (like amount of basic community-issued income)
• spending of its own treasury funds (currently restricted to KSM). see towards sustainability
• petitions (system.remark)

Therefore, no special Origin is granted which could affect the KSM token or other parts of Kusama.

In contrast to token voting on OpenGov, Encointer democracy aims at one-person-one-vote, enabled by its sybil-resilient proof-of-personhood protocol. In practice, it will be one-cycle-attendance-one-vote, which is a pretty decent approximation with some additional weight given to those who participate in the protocol more actively
