Leonardo Yvens 9db7896e48 implement from and into RuntimeValue for i8, u8, i16 and u16 (#104)
This works under the assumption that these values
are represented as an `I32` in WASM, which seems
reasonable.

Leonardo Yvens 75406dd8ff Use transmute instead of casts In RuntimeValue conversion. (#102)
Casts have arithmetic semantics, and under some build configurations
Rust will panic when encountering an arithmetic overflow.
Use a transmute instead since it's what we mean.
The previous code worked, but still I added a test for good measure.

Sergey Pepyakin 6253dd6fdf Args refactor (#71)
* Refactor TryInto → FromRuntimeValue.

Replace `TryInto<T, E>` with `FromRuntimeValue`.

The main difference is that `FromRuntimeValue` is implemented for the concrete type of the value we create, rather than on `RuntimeValue`. This makes more sense to me and seems more clear.

The `try_into` method is now implemented on `RuntimeValue` itself.

And finally, `FromRuntimeValue` has been made public.

* Impl AsRef<[RuntimeValue]> for RuntimeArgs

This impl can be used as an escape hatch if the user wants to use the inner slice.

* Little doc fixes for RuntimeArgs.

Use wasmi ValueType for RuntimeValue instead pwasm (#52)
`RuntimeValue::default` takes `parity_wasm::elements::ValueType` as an input parameter. 

This change fixes it to be wasmi's `ValueType`.
