[fpc-pascal] Default properties first draft

[Ryan Joseph]

Thanks Ben. I didn't want to submit a patch file yet (not that I know how anyways) because I don’t think it’s complete and perhaps it’s not even on the right track in terms of implementation. The compiler team seems busy now anyways so I guess this will just have to wait.

I didn’t do any extensive tests yet on big projects like the FPC RTL but there’s probably a bug I didn’t catch with default [] properties calling into my code. You should be able to compile single units though and test the syntax.

I doubt it'll get considered seriously or looked at at all otherwise. For what it's worth, I did do a checkout of your branch and then a merge to get everything fully up to date, and when I went to do a full-tree build (compiler, RTL, everything) it raised a nonsensical error in the FCL-XML package in the "dom-html.pp" file, complaining that a call to GetItem for one of the list classes there didn't have enough parameters (which is not true.)
