rewrite pre-commit, post-commit and options hooks (fixes #1250) (#1257)

* issue #1250, replace {pre,post}-receive and update hooks with a single shell script that does not require custom hooks to be a sh-script

* issue #1250, make script posix compilant

* v23, add migration script to update {pre,post}-receive and update hooks

* migration: use a more common name and rename v23 to v26 to avoid conflicts

* gofmt'ed and added copyright header

* fix SyncRepositoryHooks to also sync wiki repos
