The merge hook

At the right bottom corner of SIS webpages, we show the version ID of the running system that refers to a Git commit ID. To enable this function, we use a post-merge hook to generate a plain text commit-id.xml in the SIS/clarin folder. The commit id file is generated or updated when pulling the master branch from Github.

When updating a format-recommendation file, e.g. IDS recommendation, it important to also update the <lastUpdateCommitID>. This has to be manually updated after the changes to the recommendation file have been pushed and the commit ID for that changes has generated.
