Closes#88.
* copy method instead of using feature
Using a feature gate like "test-features" is problematic because
it is leaky: depending on situational considitons such as the
current working directory when compilation is attempted, the
feature may or may not be applied, which makes success inconsistent.
It's simpler in this case to copy a dozen lines of code than to
work out all the issues with test features.
* Start fixing compilation errors
* Switch to git version of `WasmBuilder`
* Fix compilation
* More updates
* Adapt to latest Substrate/Polkadot changes
