[Lazarus] DB aware components

[Antonio Fortuny]

Same for TImageList.
A TImageList is dropped onto a TDataModule, included in the interface 
uses, but a TToolBar does not see the TImagesList in the TDataModule.
This breaks completely the porting from Delphi.
I'm really very disapponted.

I've made another test as explained in the Wiki page 
http://wiki.freepascal.org/Frames
- build a new TFrame
- add the unit to the project units list (otherwise it is not droppable)
- drop it onto a TTabSheet of a TPageCpntrol in the main form
- drop a TSqlQuery onto the TFrame: this time, the objects in the 
TDataModule created before, are displayed in properties of the TFrame 
components (database for TSqlQuery, i.e.).
It's a long way to ...
This way does not allow to create independent TFrames and fill them with 
all pertinent components and code and that's exactly what I need.
All the TFrames are independent and dynamically created as the user runs 
thru the application.

Antonio.
