Update README.md (CadQuery#525)

In the current manual there is no clear explanation on how to quickly get started to play around with CadQuery through the CQ-editor (binaries). 

Proposed change: 
Under "Getting started" start out with the thing most people running into this project for the first time will probably want to try first: just fiddle around with CQ-editor. In the CQ-editor "installation" section I'll propose a change to add binary installation instructions (which is much easier/quicker to get started with than "the Conda way").
