only prompt with the second half of the string

will now only see the second part - the part that actually asks the question.
remove silly substitution (name is already dashed)
fix :ShareFiles
:ShareFiles actually works now
new :All and :None filefinders
typo fix
call the all/none filefinder AllFiles and NoFiles
add a "generated by" notice to generated Makefile.PL
add a "generated by" notice to generated Build.PL
add a "generated by" notice to generated MANIFEST
add a "generated by" notice to generated README
add "generated by" notice to test files

these do not have versions!  not trivial to do, so it will wait
v5.007

        - add the ability to say "dzil run --no-build" to run a command without
          building inside the dist dir
          (in other words, no `perl Makefile.PL && make`)
        - Archive::Tar::Wrapper added as a recommended prereq
        - fix :ShareFiles (thanks, Christopher J. Madsen and Karen Etheridge)
        - new :All and :None filefinders (thanks, Karen Etheridge)
        - most files generated by dzil plugins now self-identify with comments
fix dzil run
v5.008

        - fix utterly broken `dzil run`
fix changelog for renamed filefinders
