Since Rockbox Utility could only install the most recent "daily build" there is
not much difference to the most recent development build so the option was not
really useful.
Additionally update naming. Former "daily" builds are now "archived builds" and
can get installed manually (if necessary), and "current" builds are renamed to
"development build".

Doing so removes the need to loop over all targets to fill in values for
target variants in ServerInfo.
