A whole bunch of minor cosmetic changes.
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.
Add dropping privileges to all the examples.
Add statgrab_init() call to the examples. If people are going to copy them I guess we should try and make them correct :-) Also tidied up whitespace in the examples.
Fix getopt() return value.
