Save the 'From' header received in a REGISTER message so we can show it

e.g. in the Manager interface. This information is available as
a callerid (or something like that) during a call, but not when a
device is registered but silent.
It may be useful to have it available e.g. when developing a user
interface/operator panel, to map numbers to names.

experimental, so not committed to 1.4
