Create new quickstart tab for RiTa/RiTaJS on website

[dhowe]

We need a new tab on the website called 'quickstart'. It should have the following subtopics, each linked to the install instructions (can take these from the various READMEs)

Install (Java) -------------------------------------------

-- as standalone program (use main) -- as library in Processing -- as library in Processing on Android -- as library in Android (standalone-app) -- via maven -- instructions for RiWordNet

Install (Javascript) --------------------------------------

-- on node (from npm): https://www.npmjs.com/package/rita -- on node (from github): https://github.com/dhowe/RiTaJS

-- in the browser (standard): https://github.com/dhowe/RiTaJS -- in the browser (with browserify) -- in the browser (with bower) -- in the browser (with p5.js) -- in the browser (with ProcessingJS)

Missing 2 instructions for now:

• in the browser (with browserify)
• as library in Android (standalone-app)

Because they are not working.

OK. added Android Studio and browserify installation instruction #91

browserify is not working but the installation instruction will still be the same #84

please verify
