Add ability to change connection for formmaker

[miscbits]

This resolves #7 when using getTableColumns and fromTable and also resolves a glitch in InputMaker

                $final = $final->$realProperty;

Could return PHP error: Trying to get property of non-object because config['object'] could return an array making the line similar to something like

array('a'=>'0','b'=>'1','c'=>'2')->a

which will return the same error.
