#26 Memory leak + Fix pt. 2

[Mikael]

Another, separate memory leak, and the modifications
necessary to remove it:

Inside of XpXSLT.inc, TXpXSLForEach.Execute on line
7240, if 'oNodes' (a TXpNodeList object) contains '0'
(zero) entries, the method EXIT's without free-ing
'oNodes' (if it DOES contain at least one entry, it
will be free'd correctly.

Fix - currently lines 7239 and 7240 look like this:

// --------------------------------- //
if oNodes.Length = 0 then {!!.55}
Exit; {!!.55}
// --------------------------------- //

Modify the file by adding an additional two lines:

// --------------------------------- //
if oNodes.Length = 0 then begin {!!.55}

oNodes.Free; // New: free the TXpNodeList
Exit; {!!.55}
end;
// --------------------------------- //

..which ensures the TXpNodeList object is correctly
free'd if the method exits prematurely
