Fixes Issue #575.
Removes DOMImplMozilla's reliance on getBoxObjectFor in getAbsoluteTop/Left.
getBoxObjectFor changed between 1.0.7 and current Mozilla making it hard
to provide consistent behavior in hosted and web modes. Also, the new
implementation returns an offset that is incompatible with our convention
for gwtAbsoluteTop/Left. This also adds a simple test to cover
getAbsoluteTop/Left.
