* First effort

* API versioning

* Introduce validate_transaction

* Introduce the API plus fixes.

* Docs

* Typo

* Add longevity parameter to transaction validity info.

* Make `system` module renamable in `impl_outer_event!`

* Implement `construct_runtime!` macro

This macro generates code for calling all the common `impl_outer_*` macros.

* Add documentation

* Fixes wrong declaration of `contract`

* Update dependencies to work on `no_std`

* One more `Cargo.lock` update

* Address comments

* WIP

* Direct return of output data.

* Docs and renamings.

* Add get_storage test.

* Overwrite the scratch buffer.

* treasury: use 'mutate' and 'retain' to avoid creating a new vec

* treasury: check the underflow case

* bugfix: balances::transfer for new_account

issue:#722
would_create flag should depend on dest, not origin.
change 
```rust
let would_create = from_balance.is_zero();
```
to 
```rust
    let to_balance = Self::free_balance(&dest); 
    let would_create = to_balance.is_zero(); 
```
in the other hand, provide `fn new_test_ext2()` and let `transfer_fee=10`, `creation_fee=50` for test case

* Update lib.rs

* Update tests.rs

* Make `impl_outer_origin!` support generic `Origin`s (#732)

* Make `impl_outer_origin!` support generic `Origin`s

* Support empty outer origin

* Contracts: fix transfer function. (#733)

* Remove dependency on the parity repo (#734)

* Fix test

* Anothe fix

* Make `impl_outer_origin!` support generic `Origin`s

* Support empty outer origin

* Improve and simplify `decl_event!`

- RawEvent is not required anymore to be written in the defintion
- Events with and without parameters are now supported everywhere

* Make `decl_event!` more flexible with the automatic naming of generic parameters

The macro will now automatically derive the name of a generic parameter
from the trait type name, if no explicit name is given.

`where Balance = <T as Trait>::Balance` can be simplified to
`where <T as Trait>::Balance`.

* Adapts to latest refactoring changes

* normalize decl_storage

* dispatch the function call

* add test case

* fix the root case

* add system

* fix the typo in unit test

* fix the doc generation for decl_module

* fix the unit test due to the interface change
