• added "MySQL Help" to the MainMenu > Help submenu

- it shows the MySQL Help TOC of the front most tableDocument mysql connection, i.e. each tableDocument has its own Help window (due to the fact that the Help is version specific), and makes it the keyWindow
- changed the way for getting the mySQLversion into the CustomQuery; now a new tableDocument set it via [customQueryInstance setMySQLversion:foo]; the other way was to unsafe regarding to get the version if MySQL Help was invoked via MainMenu 
• Help window and Create Table Syntax window will be released while closing the tableDocument
