Bug fix of max length stuff in LBF forms and layout engine.
--New fields created in layout engine use the TEXT sql type, when applicable.
--Added fld_rows to hold number of rows(height) for textarea datatype
--Copied this value from max_length to fld_rows
--Added the size height and a maximum size (max_length) entry in layout editor
--The max_length entry value is what is used for validation
--If it is set to 0, then no size checking
--Set all the entries based on a sql TEXT column to have a max_length of 0
--Set all textarea and nation notes datatypes to have a max_length of 0
