Unmerge item-info expansion

I merged it, didn't realize that there'd be a problem with small terminal sizes, so here's the cleanup.  My apologies, all.  As requested in, and fixes, #6274.

Revert "Merge branch 'iteminfo' of https://github.com/goron111/Cataclysm-DDA into goron111-iteminfo"

This reverts commit 4a852cc9e2f7c76aee6845172adfb70efe625973, reversing
changes made to 9f88213ad96b41861cdcdfc05e85b1ad6cabdbf8.

And I designated a trial branch for a reason.  Let's see if I needed it!  (Looks like I didn't for that reason.  Makes the PR easier to do, though.)
