While fixing MDL-30170, the following tiny usability details were
improved along the way:
* the maximum length of the peer site title and the hostname is now
validated (this was actually a real bug as the default value is pre-loaded
from the peer) so the admin gets a nice validation error instead of
the database write exception when trying to register a host with a
longer site title.
* hard-coded English string 'All Hosts' is now localized
* the hostname link in the list of MNet peers leads to the peer itself
