Bug 23602: (follow-up) Improve tooltip formatting

This follow-up changes the formatting of the tooltip to add a newline for
library limit.

To test, apply the patch and go to Administration -> Item types.

In the table of item types, find one with library limitations. Hovering
over the "# library limitations" test should trigger a Bootstrap-styled
tooltip showing the library name and code, one per line.
