Remove clutter. CHANGES should be readable by USERS.

- SVN revision numbers are not relevant to users. Mention them in SVN
changelogs.

- Fixes for compiler warnings are not relevant to users unless they caused bugs.

- Bug reporters need no credit in CHANGES -- thank them in bugzilla, on
mailing lists, and in SVN changelogs as appropriate.

- The mod_ssl change did not fix a bug, per list discussion.
