[Lazarus] DBGrid - Patch review request

[Gabor Boros]

Hi All,

I do not want to disturb the developers but don't know which is the best 
practice. Wait or not wait. For example issue 28597. Wait more than a 
year then wrote to the list about it and Zeljko fixed on same day (on 
Saturday!).

So, I created a patch for help record reordering feature in my 
application with DBGrid and an example project for demonstration. Please 
review, comment (good, bad, never ever), ...
