refactor(project): v1.0.0

now uses separated backends:
jQuery.ajax backend and Node's request module unmerged to distinct projects

Like some months ago, this project is a basic wrapper/handler for various backends, which are available as separate modules.
this v1.0.0 is a kind of "back to square one" in some ways, but with more search and thinking about it.

docs: minor documentation features
test: all tests refactored for this new version
