This fixes Apache access to json files in koha-tmpl for non-package installs. This causes issues for system preferences where there is a pick list for database columns.
Bug 22844 introduced a pick list of database columns for system preferences where such a list was required. This list is in a plain json file under the templates directory. This works fine for packages, but because of bug 9812 (which limited browser access to selected files) those directories are not accessible to the outside world for both standard and dev type installs using the make process.
