Document browser improvements, and Racket using them
We have a new "manual lookup" command, and Racket now displays a doc browser buffer for help with a button activating it. In the process, we've cleaned-up a little mess in geiser-eval.el and geiser-doc.el, and refactored the affected Racket modules. Next in line is providing manual lookup for Guile.
