bootstrap.native 3.0.6

Components as modules now available, other improvements

on Node.js NPM

Changes:

• changed all util and imports structure for more accurate bundles
• addressing #381, added more build scripts, now dist/components/ folder holds UMD and ESM modules for all components, thanks @lpar
• removed dependency on shorter-js for events handling, class manipulation, and more, see commit file changes
• removed the tryWrapper due to some inconsistency error reporting, despite the benefit it brings
• Code cleanup
