Remove Utils.js dependencies

Removal doesn't seem to make absolute sense. Some of Utils.js libraries are really useful, e.g.:

• event manager
• looper
• thin wrappers or polyfills*

I should consider restarting development of library with utilities.

*it is still debatable for me if libraries should a) depend on polyfills (e.g. using bower), b) include them, c) mention them only in documentation
