Dashboard: VM meters and sparklines, slackpkg tile

sbb-remote 0.3.0 adds CPU busy % (two /proc/stat samples), RAM total
and available, disk / total and free, and the last slackpkg update
(LASTUPDATE) and package change (/var/log/packages), replacing
disk_free. The Dashboard shows a VM card with meters for CPU, RAM and
disk / (accent, warning from 80%, critical from 90%, value always
printed) and CPU/RAM sparklines from this session's polls, and a
slackpkg tile in place of VM load.
