[MOD] Changes that should allow fulltext search in InnoDB, for MySQL 5.6 or higher.
Installer has been changed, so the fulltext image definitions are included, if the engine supports fulltext search.
The fulltext index definitions are placed in a new file.
TikiDb::isMySQLFulltextSearchSupported implements the check used. 
Test on MySQL 5.6 is still pending.
