don't add lisp/other to load-path

Adding file .nosearch in that directory makes it less likely that it
is accidentally added to the load-path.  Users can still add it there
manually.  Some of the files in this directory are also available
separately and it can be really confusing for users when they install
a package explicitly but an older version bundled with some other
package is loaded instead.

Also since you appear to be the author of some of these bundled packages or have at least made considerable contributions in the past could you please consider making some of these available as separate git repositories.

Thanks!
