* 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

* 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
