Refactor / simplify Lerna build process

[Havunen]

It would be nice implement new lerna build pipeline.

When running npm run publish it should do following:

1. Bump version of all packages
2. Run inferno js build script npm run build
3. Run benchmarks build script npm run benchmarks
4. Run tests
5. Release Github tags and NPM packages

If any of the above steps fail it should stop the process.

Currently its doing build and package version bumping multiple times due to legacy scripts and this was not possible in old Lerna version.

We should test if we can refactor build script to use multiple rollup output formats instead of spawning multiple parallel processes to work same time.
