sustainable community treasuries: refill from CII issuance and fees

[brenzi]

In the current protocol design, community leaders are expected to fund their activities from external sources (like grants from Encointer Association or donations). If they want to spend CC, they need to buy it from somewhere. This has the nice side-effect that it causes circulation of CC, but other designs would be imaginable. IT seems intuitive to send a fraction of money issuance to communitiy treasuries. The community should then be able to vote on who should control spending of their treasury

Moreover, the global protocol needs to be maintained and it appears fair to share this load among active communities

Possible Solution:

• whenever participants claim their cycle rewards (CII), an additional fraction of CC is issued on behalf of the community treasury
• tx fees go to treasuries instead of being burned
• the community treasury is controlled by a democratically elected account (preferably multisig among active community leaders)
• even faucets could help fund the treasuries: either upon creation or upon drip, a fraction of the faucet's token could be transferred to the treasuries. Upon creation would be more attractive for community leaders
