Consider changing the licence to AGPL

[13hannes11]

The MIT license allows fairly liberal modifications but this can also mean hostile takeovers of the quadratic software by a competitor or a large company. I recommend to change the license to AGPL because that ensures that anyone running a modified version of quadratic will need to also provide the source under the same license to users.

Also it could give trust to contributors as no company can just run away with a product originating from quadratic. I'm not a lawyer so take this all with a grain of salt.
