version bump to 0.1709

new release because we haven't done one in a while and we're putting in
fixes.

Hopefully this won't break anything.

version bump

bumping to 0.1705

version bump for ip => ip_address fix

Version bump to 0.1703

this is version 0.1702 with speed changes

perl version bumped to 5.12.5

There was a change between 5.10 and 5.11 to the way filehandles work.
Lots of the code depends on being able to use getpos.  Rather than
figuring out what broke between those two old versions, I've set 5.12.5
as the minimum version.

That means this won't work on Centos v5, but it's been broken for that
platform probably from the beginning, now it is documented.

adding make_immutable to all classes

From the Moose best practices.  This speeds up the code by a factor of
10 or so, for the large dhcpd.conf file I was testing on.

Also bumping release to 0.17 because I screwed up and released with a broken
test

version bump to 0.16
