Code cleanup (#120)

* Lots of code cleanup

* Cleanup parse-options tests
  - Rename objects for clarity and inline unneeded objects
  - Remove unneeded tests
  - Use Object.keys().length instead of a custom function
  - Use typeof === "object" instead of a custom function that checks the prototype tree as well, since we don't expect anything but an object literal.

* Remove old switchFallback code

* Remove polyfill for Function.prototype.bind

* Inline small functions

* Add more documentation and tests for options.currentUrlFullReload
  Closes #17

* Update package.json
