* 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
Clone attribute nodes before setting on `oldEl` to prevent the following error:
```
DOMException: Failed to execute 'setNamedItem' on 'NamedNodeMap': The node provided is an attribute node that is already an attribute of another Element; attribute nodes must be explicitly cloned.
```
