This ensures the routerconsole changelog multi-column view doesn't wrap
unnecessarily.

This ensures these changes are applied to Debian installs, where we get JRobin
from the package manager instead of our bundled source.

The padding and grid stroke changes to RrdGraphConstants have not been reverted,
because there is no API provided to alter those values. This will result in a
minor difference between Debian and non-Debian graphs, and if a user shares
those graphs, it will reveal the fact that they have installed the Debian
package. This is acceptable, given that the graphs themselves inherently reveal
significantly more private information than that.
