Fixing Case-Sensitive Class Names

As per [this answer](http://www.magentocommerce.com/boards/.../viewthread/207423/#t413719) and my own experiences, this fix makes it possible to compile sites on a case-senstive filesystem.

On a side note, it appears line ending style has been fixed in these files as well, hence the larger than normal change log. I'll link to the changed lines (only 4 of them).
