Changes by Nick Fetchak:

- IE8 standards mode compatibility

- VML elements now positioned behind original box rather than inside of it - should be less prone to breakage

- Added partial support for 'box-shadow' style

- Checks for VML support before doing anything

- Updates VML element size and position via timer and also via window resize event

- lots of other small things
