added database.txt documentation; currently only describing Django-related features of MySQL versions. As of this commit, there are four known test failures due to (a) no transaction support with MyISAM storage engine and (b) MySQLdb automatically creating decimal types for Django's "float" field. git-svn-id: http://code.djangoproject.com/svn/django/trunk@4724 bcc190cf-cafb-0310-a4f2-bffc1f526a37
