Create new version of library based on rollup with CI/CD on TravisCI

[mtronix]

Referring to the conversation with @bebraw I will prepare CI/CD on Travis CI and basic scaffold of app with rollup and Typescript.

CI/CD should build app, test it (tests will be implemented in future) and publish it on NPM automatically (only from master branch)

The reason for using rollup is to easy create 3 independent packages (CommonJS, AMD and UMD).

Next version of app will be written in TypeScript.

I am still developing basic version of app. If anyone has any comments source code is here: https://github.com/mtronix/assert.js/tree/feature/new-version-of-library

I must rethink two things:

1. error handling - it will be good to catch assertions by type or by id (required in runtime environment)
2. value rendering - we must create thing which render values in human readable format

PR with 1.0.0-alpha is submitted (@bebraw can you review? I cannot add you as reviewer in PR)

TODO:

• add tests (probably mocha), also add performance tests
• add more number assertions (lower than, greater than, between etc.)
• add CI/CD with TravisCI (Github Pages deployment is broken with dpl 1.9.0 travis-ci/travis-ci#9312 stops me a little bit)
