- rework the README a bit, install notes may still need some fixes
- note: run daily.sh as _librenms after installing the new version to
update schemas, you will see errors when you try to login if you don't
do this.
- note: some things moved from symbolic links to real files which
pkg_add -u doesn't cope with (this is the same case as "exotest" in
regress/usr.sbin/pkg_add). pkg_delete then pkg_add when updating.
@ask-update is used in the plist to try to warn you and ask you to
cancel during the update in this case.
