new version 0.1.2

- IE<8 shim for Element.prototype.hasAttribute
- Internal function ‘getStyle’ fix to differentiate better between when
to use window.getComputedStyle and object.currentStyle
- Fixed internal function ‘getText’, which can better differentiate
between when to use object.textContent and object.innerText
- Fixed bug in internal function ‘handleEvent’ to differentiate between
object.attachEvent and document.addEventListener
- Added ‘class’ as an option when only passing in one argument to
.get(), which will avoid having to rely on
element.getAttribute(‘class’), which won’t work in legacy IE
- Fixed bug in .get() that would default to element.getAttribute() if
internal function ‘getStyle’ returned a falsy value when only passing
in one argument
- Added more specificity to get attribute ‘class’ when passing in
‘attr’ as the first argument and ‘class’ as the second argument when
passing in exactly 2 arguments to .get()
- Identified several possible bugs
