v2.0 - Switch to Chrome Engine

Phantomas (https://github.com/macbre/phantomas) is currently switching its engine from PhantomJS to Chrome. It should fix some long standing bugs and also bring some brand new possibilities to YellowLabTools.

The first step (v2.0) will not bring new rules. It will concentrate on this engine change, make sure everything still works correctly, update installation docs.

However, the JS Timeline tab will most probably disappear. It is rarely used, rarely understood and very CPU intensive.
