[PATCH] {diff,merge}tool: rename helpers to remove them from tab-completion

[David Aguilar <davvid@gmail.com>]

Users should never run difftool-helper or mergetool-lib directly,
so rename them to *--helper and *--lib.  This keeps the helper
scripts from showing up when using bash tab completion.

This is based on the 'pu' branch + the patches
I sent out earlier.
