Unreleased

Keyword indexed is now optional for word typed (bool, int, address, ...) event arguments.
State variable pretty printing now produce 'a, 'b, ... instead of '1, '2, ....
ACI is restructured and improved:
- state and event types (if present) now appear at the top level.
- Namespaces and remote interfaces are no longer ignored.
- All type definitions are included in the interface rendering.
- API functions are renamed, new functions are contract_interface and render_aci_json.

stateful annotations are now properly enforced. Functions must be marked stateful in order to update the state or spend tokens.
Primitives Contract.creator, Address.is_contract, Address.is_oracle, Oracle.check and Oracle.check_query has been added to Sophia.
A byte array type bytes(N) has been added to generalize hash (== bytes(32)) and signature (== bytes(64)) and allow for byte arrays of arbitrary fixed length.
Crypto.ecverify_secp256k1 has been added.

Address literals (+ Oracle, Oracle query and remote contracts) have been changed from #<hex> to address as ak_<base58check>, oracle ok_<base58check>, oracle query oq_<base58check> and remote contract ct_<base58check>.
The compilation and typechecking of letfun (e.g. let m(f, xs) = map(f, xs)) was not working properly and has been fixed.

let rec has been removed from the language, it has never worked.
The standalone CLI compiler is served in the repo aeternity/aesophia_cli and has been completely removed from aesophia.

Add Crypto.ecverify to the compiler.
Add Crypto.sha3, Crypto.blake2, Crypto.sha256, String.blake2 and String.sha256 to the compiler.
Add the bits type for working with bit fields in Sophia.
Add Namespaces to Sophia in order to simplify using library contracts, etc.
Add a missig type check on the init function - detects programmer errors earlier.
Add the ACI (Aeternity Contract Interface) generator.

Use native bit shift operations in builtin functions, reducing gas cost.
Improve type checking of record fields - generates more understandable error messages.
Improved, more coherent, error messages.
Simplify calldata creation - instead of passing a compiled contract, simply pass a (stubbed) contract string.
