Bug 26602: Don't export "actions" column

This patch add the noExport class to all "Actions" columns in the
codebase.
It's a stupid search and replace, maybe the class is added to table
where there is no export button.

Test plan:
Search tables where the export button is available. Confirm that the
"Actions" columns is not exported.
Example: /admin/branches.pl, /admin/cities.pl
