bind::zone - purge files when not declared in puppet
add support for Ubuntu
Merge commit 'e3fdfb9f8b9bb9ec12ce5d0bd3bc240f48fcfd48' into test-bind
file renaming to be compliant with recommended module structure.
Add bind::txt
Add bind::ptr
Create PTR records from A records
Change variable name (don't use $fqdn)
Make sure wrk are unique resources, don't activate PTR by default
default=false for ptr in a.pp
Do not use  when calling bind::ptr in bind::a
Fix PTR by calculating arpa zones with IPAddr.new(host).reverse
switch from common::concatfilepart to concat[1]
