* 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`.
