Make 10.21.0 releasev10.21.0

Adds two small library/menuconfig improvements:

 - Commit 7992519 ("Always strip trailing whitespace in 'MenuNode.help'
   and __str__()") tightens up the format of strings a bit, and
   documents it.

 - Commit b810bda ("menuconfig: Support HOME and END in the jump-to
   dialog") adds support for some keys that were missing from the
   jump-to dialog.
