I've attached a few fixes for typos my IDE spell-checker helped me find. (I hadn't yet configured it to turn off spell-checking!)

A couple of notes:

1. I changed "propogate" to "propagate" in the comments for Dialect, but not in the method name, because it's a public method and so would obviously be a more major change.

2. Here in jira, you remind me that patches should be in 'svn diff' format, which is a good reminder. The "details" link, however, is broken, pointing to a page from the old hibernate site.
