NodeJs, increase compatibility

# RollUp
Rollup modifies the Code resulting into potential breaks for jspdf.

jspdf.js (2172:84) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
node_modules/cf-blob.js/Blob.js (211:84) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
node_modules/cf-blob.js/Blob.js (211:100) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
node_modules/file-saver/FileSaver.js (176:4) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
libs/deflate.js (2056:3) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
libs/png_support/png.js (469:46) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
libs/polyfill.js (196:85) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten
The following options have been renamed — please update your config: moduleName -> name

E.g. in Blob.js
}(typeof self !== "undefined" && self || typeof window !== "undefined" && window || this.content || this));

https://github.com/eligrey/Blob.js/blob/master/Blob.js

Will be changed to
}(typeof self !== "undefined" && self || typeof window !== "undefined" && window || undefined.content || undefined));

obviously results into breaks in nodejs, wenn undefined.content is tried to be solved, which results in an error.

Various calls of window-Object in jspdf should be removed or made compatibly with node.

I bumped into a similar problem today:

I am using jspdf.js as of https://github.com/MrRio/jsPDF/blob/master/jspdf.js and insert it directly in to my project (without any rollup etc.). This is done using Opal builder.

Thereby I found that jspdf.js does not extend module.exports but replaces it.

This should be fixed

In my system , I changed https://github.com/MrRio/jsPDF/blob/4e224d8bb2a7d690d59149fb64bd4203890d202e/jspdf.js#L2280

to

    module.exports.jsPDF = jsPDF;

Seeing 68 open Pull requests, I do not want to open number 69 :-)

Sorry, some of this is from my libraries. It will be fixed soon!

Edit: All fixed on my end.

If @eligrey updates his repos and if we can convince @Rob--W, then these rollup errors should be all solved by our PR #1592

[Uzlopak]

The current project admin of zip.js seems to be unwilling to make the necessary changes. I took the latest version of the Deflater and applied the changes to it. We are still independent from the zip.js project. But I think it is ok.

If FileSaver.js is modified, that rollup errors should be finished and PR #1592 should be merged.

navigator-Object is a Browser-only Object.

So e.g. the line if (navigator.getUserMedia) { has to be changed to if (typeof navigator === "object" && navigator.getUserMedia) { to stop throwing an error in nodejs
