Currently the 'channels' setting of a 5G radio gets overwritten or
deleted even if the 'preserve_channels' option is enabled. Don't touch it
if 'preserve_channels' is set.

"not self.title" doesn't work because of "self.title = title or """

The other bugfix which made this element inherit from AbstractValue
caused AbstractValue:validate() to be inherited aswell

Now added an if so validate only runs if a datatype is set
(since Element is meant as a generic way to extend web-model without
modifying web-model - also to add custom inputs - just hiding it behind an if sounds like a sane solution)

This reverts commit 543eb178.

Restores the dns caching configuration that should be feasible, since we
now require around 8 MB of flash.

We migrate to dnsmasq-full, while disabling most of its features.
Notably, dhcp and dnssec are compiled in, while other features of the
full variant are deselected.
