Various enhancements.

To Do:

  • Apply updates to postgres sql schema
  • Implement upgrade routine
  • Delete zone files from slaves. Currently a zone can be removed and re-added with a lower serial (e.g. re-added on same day) and the slave won't transfer it because it has the pre-existing file with higher serial.

Delete zone files from slaves when deleting zones
ade2c8a 
	This is admittedly over the top. Reasoning follows:
	To reliably delete a zone file, we need to reload the config first
	with the deleted zones removed. For example, if BIND is restarted,
	it will re-create missing files for zones it is still configured to
	carry. For this reason, I moved zone file deletion to commit.php.
	Since we are only doing this at commit, we could be deleting many
	zones. We need to SSH into multiple hosts, and delete several files
	on each. For this to complete in a reasonable time frame, it is best
	to use xargs. xargs also provides the safety of its -0 option. Now I
	have a reasonable-sounding excuse to write some fancy and fun non-
	blocking I/O code to solve a trivial problem ;-)
