* bugfix: Check for existing hostnames on the network in DHCP reservations
fixes#216
*additional check for existing hostname when creating new DHCP lease.
checks hosts_olsr file if entered hostname already exists or not on the connected network(s).
outputs info saying such and gives advice to prefix hostname with callsign.
* change to use =~ /\s$host\S/i
* Reworded warning message
* moved the position of the hostname check to only when you click "add" on the DHCP leases page.
this stops it checking all the previously entered hostnames.

* removed some commented lines that were not needed
* actually fix the typo I saw in help.html file.
with low memory conditions, typically on 32Mb RAM, the
device would become unresponsive in hours to days. The
symptoms only occured when no RF links. iw processes
would hang in Zombie state. Updates to use iwinfo where
possible and avoid using both iw and iwinfo. crontab
script is implemented to detect Zombie processes and free
up resources in the reduced chance the symptoms are still
occuring.
* config change to make uhttpd listen on port 80 and 8080
* add port 80 to tunnel firewall rules
* add port 80 to tunnel firewall rules in config, update help
* firewall rules for wan + dtdlink
