Added CRC comparison

The current code just uses table id, subtable extension and version number to
check if the section has been seen before. However, this comparison is not
sufficient, causing actually new tables being dismissed.

The attached patch retrieves the CRC and compares those as well.

The patch is based on a discussion I had with Zaheer Merali.
