Support for Tolk Language: next-generation FunC
* the user is able to create contracts in three languages: FunC, Tolk, Tact (both from UI and command-line) * templates 'empty' and 'counter', like for FunC and Tact * contracts are compiled with tolk-js, a WASM wrapper, like func-js * no file like 'stdlib.fc' exists, stdlib is embedded into Tolk distribution Co-authored-by: krigga <[email protected]>
