Improve (describe-personal-keybindings) output

Create *Personal Keybindings* by with-output-to-temp-buffer. It
redirects standard output to the buffer and display it in help mode. So
we can get help mode keybindings such as "q" for free.

Quote the command-desc output so that it is made into a hyperlink.

highlight use-package before typing package name
cl not needed since flet was removed in f96427a
