More EPUB Scoping Fixes (#691)

* Added better handling around when importing css files that are empty. Moved comment removal on css files to before some css whitespace cleanup to get better matches.

* Some enhancements on the checks to see if we need the bottom action bar on reader. Now we don't query DOM and have something that works more reliably.
