Overall update

[kaosat-dev]

Hi Gary ! how are you ? :) This PR adds a coat of 'fresh paint' to the translator and updates a number of things:

• removes requireJs in favor of common.js (for both code and tests): this makes code more readable and work out of the box in node.js, and removes a dependency
• a bit of code cleanup and refactoring
• web build are now done via browserify
• updates dependencies : removal of underscore for lodash (same , but more up to date), fixes issues with changed apis in dependencies
• add npm commands for things like building the parser, the output distributables etc
• remove various un-needed libs , depenencies etc : more 'lean'
• I most likely forgot a few things

Some things definitely broken. lodash.rest is not the same as underscore.rest. I'm trying to make converted output more readable, you can wait for a fix from me or fix it yourself, if you want.

Take a look: https://github.com/jscad/openscad-openjscad-translator/blob/master/src/openscad-parser-ext.js#L39

@apla wow thanks for finding that one ! I thought I had fixed all of them ! Will do asap ! Weird, all tests ran fine btw, plus openjscad + some extra tests did not pick it up

Fixed, there was another one in PrimitiveModules.js please let me know if you see anything else! And anything that makes output more readable is a good enhancement !
