Log Message:	Alter the licensing of libstatgrab. The library part is now under the LGPL, whilst the tools/examples are under the GPL. Both licenses are included in the distribution (and are both now in CVS). Also made a minor alteration to the webpage where it said everything was licensed under the GPL.
