[fpc-pascal] JSON SAX-based reader

[Stefan V. Pantazi]

Thank you for this, Michael. I think it is wonderful work.

I've done some old tests of the new implementation and it looks very 
good. The only failed tests were related to date and time 
representation. This appears to be fixed in the new version. Most 
importantly, I see no memory leaks when parsing fails due to malformed 
JSON, and that is great!

The only fixes I had to do to my own software to accommodate the new 
implementation, were:

1) comment out the "Strict" property of the TJSONParser (it appears it 
no longer exists); I used to set it to false, to allow for more 
flexibility in JSON syntax.

2) add the missing procedure SetKey(obj:TJSONObject); to TJSONConfig 
since it was removed from the new version of jsonconf.pp; anyway, in 
this particular case, it may be me that has to rethink and simplify my 
use of the json config component that does not need SetKey.

Hope this helps,

Stefan
