[doc] missing documentation

[glensc]

http://search.cpan.org/~nierlein/Monitoring-Plugin-0.39/lib/Monitoring/Plugin.pm#CONSTRUCTOR

there's no documentation for version, blurb, license, extra, plugin, timeout parameters

as for example i was looking where to put information about homepage and where to report bugs and copyright years and author.

---

for homepage and bugs url, i just appended to blurb:
glensc/nagios-plugin-check_raid@cd17820

for license and copyright did not find good solution: i do not want to replace license key, i like that default GPLv2 is printed.

here's example how my plugin worked before starting to use perl-Monitoring-Plugin, and after

➔ ./check_raid-3.2.5.pl --help | head -n10
