Make Demo app compile without FastMM

[RomanYankovsky]

Maybe we need some sort of conditional compilation to support both.

[sglienke]

Do we? FastMM is a de facto standard and open source. Should be no problem with requiring it. Anyway just remove the code that needs it - it was mostly there to show you the differences that the string interning makes.

[RomanYankovsky]

It is nice to be able to show the differences that the string interning makes, but I think, by default, demo app shouldn't require any 3d-party libraries. It's just a demo app and every additional 3d-party reference makes it harder to build and run.

and pls without generics TArray, IOUtils,Diagnostics for delphi 2009 compatibility
