pillar.example that should generate something close to the sample configuration
WIP: Turning dhcp.conf into a jinja-template...

--HG--
rename : dhcpd/files/dhcpd.conf => dhcpd/files/dhcpd.sample
more pythonic pillar-vars (dynamic-bootp -> dynamic_bootp)
more WIP template for dhcp.conf
no more TODOs in pillar.example
completed basic template for dhcpd.conf
(enough to rebuild the sample configuration).

Also moved the "subnet"-block into subnet.jinja
to prevent repetition inside "shared-network"-
blocks.

Oh, and a .hgignore to ignore vim's "*.swp".
minor update of README
