Subject: [PATCH] Bug 32539: Add exception handling to plugin hooks in template
 plugin

This change wraps Koha plugin hook calls with exception handling
within the template plugin for Koha plugins.

Test plan:
0) Apply patch
1) Install a plugin that provides "opac_head", "opac_js",
"intranet_head", and "intranet_js" with Perl errors in them
2) Load an OPAC page
3) Note that the OPAC page loads correctly
4) Load a staff interace page
5) Note that the staff interface page loads correctly
