[Lazarus] TStringGrid sort symbol in TitleButton

[John Landmesser]

Hi Zeljko,

think of a *.csv file and StringGrid.LoadFromCSV...

No columns defined in StringGrid, they will be created "on the fly" and 
user wants to sort a column by click on columnTitle.

There are default arrows that only show up if you define at least one 
column and thats not ok i think!
