bug 214519 - Allow appending strings to CREATE TABLE statements (Allow 
MySQL engine=InnoDB)

Adds creation-suffix tag to eclipselink-orm.xml tables, and a new 
"eclipselink.ddl-generation.table-creation-suffix" persistence property, 
both of which allow string values
to be appended to CREATE TABLE statements.  see 
http://wiki.eclipse.org/EclipseLink/DesignDocs/214519 for the design doc
