* Change contract key maintainers to have template argument in scope
More precisely, change the contract key type class we desugar the surface
syntax to such that the maintainers function has the template argument
in scope instead of the key. The compiler rewrites all references to the
template argument into references to the key and fails whenever that is
not possible.
* Add TemplateKey class to desugaring module
* Make template key check slightly more lenient
* Fix TODO descriptions
* draft of active contracts streaming - still WIP
