Incorrect regex for static DHCP

[mtnmkr]

The hostname validation regex for static DHCP leases prevents assigning perfectly valid hostnames, per the guidelines in RFCs 952 and 1123.

Current regex: /^[a-zA-Z0-9]+$/
Should be more like: /^[a-z0-9][a-z0-9\-]*$/i

This shouldn't be difficult to fix.

Technically they can't end with a hyphen either, more like:

[A-Za-z0-9]|[A-Za-z0-9][A-Za-z0-9\-]*[A-Za-z0-9]
or
[A-Za-z0-9]([A-Za-z0-9\-]*[A-Za-z0-9])?

Good point.  So then /^[a-z0-9][a-z0-9\-]*[a-z0-9]$/i should work.  Either way, it should be a pretty easy thing to fix.  Until then, I guess I won't be able to assign static leases for my servers. 

I guess I could always use the OpenWRT section, assuming it bypasses the input validation on the Almond side.  It's not that big a deal since I can't really swap all my servers over yet anyway.
