* Fix wasm build + full example build

this requires parity codec implements codec for core::marker::PhantomData

* patch parity-codec link to github branch

* improve internal names and fix instance prefix

* Fix in macros

* add test modules for support

this allow to test for construct_runtime as well.

The reason to have put that in another crate is:
* if we put test in `tests/` dir of srml/support then decl_storage fails to get
  srml-support access because it believes it is inside srml-support
  crate and so derive access to `quote!{ crate }` but this is wrong
  (and I don't see any way to prevent that, and it only bother us so I
  don't think that matters that much)
* if we put test inside lib.rs then contruct_runtime cannot be used
  because it call some macros that are defined with macros
  (decl_outer_event and decl_outer_origin) and thus rustc complains.

* defaultinstance to its own struct to avoid errors

* enforce <T, I> for Event and Config, impl test

* add origin, log, inherent to test

* test more code generation

* basic storage test

* fix typo

* rename a few imports and field

* delete wip test in example and runtime

* change default prefix to make it backward compatible with test

* rename Instance to I and Instantiable to Instance

note: the name of generic parameter I is only enforce by decl_module!
and this could be rewritten
