nsis.pas changes submit

Hi,

Here goes my litle addition to NSIS. In attachment I have litle imporvements over nsis.pas Delphi plugin code:



(sory for not having patch.)

Two additional functions here:
* LogMessage(text: string) - to send text to DetailPrint window
* Call(function: string) - to call back NSIS script function which adress is retrieved before plugin call with GetFunctionAddress.

Hope it will be useful.

Can you create it as a patch for tracking and credit?

Ok.. here it is.
