parse-element.js checks if the element was already parsed by
checking for the `data-pjax-click-state` attribute. However, this
attribute was not added until the link is clicked.
Originally, there was a separate attribute, `data-pjax-enabled`,
which tracked if the element was parsed already, but that was
changed in 9a86044.
This commit merges the attributes for mouse clicks and key presses
into one and adds that attribute when the element is initially
parsed.
* 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
