all src: (please read full commit message): allow local admin-defined hooks

You can now add your own hooks into src/hooks/ and they get propagated
along with the update hook that is present there now.  Please read the
new section in the admin document, and make sure you understand the
security implications of accidentally fiddling with the "update" script.

This also prompted a major rename spree of all the files to be
consistent, etc.  Plus people said that the .sh and .pl suffixes should
be avoided (and I was feeling the same way).  I've also been
inconsistent with that "gl-" prefix, so I cleaned that up, and the 00-
and 99- were also funny animals.

Time to get all this cleaned up before we get 1.0 :)

So these are the changes, in case you're looking at just the commit
message and not the diffstat:

    src/pta-hook.sh -> src/ga-post-update-hook
    src/conf-convert.pl -> src/gl-conf-convert
    src/00-easy-install.sh -> src/gl-easy-install
    src/99-emergency-addkey.sh -> src/gl-emergency-addkey
    src/install.pl -> src/gl-install
    src/update-hook.pl -> src/hooks/update
