Broken template display for invalid static pages instead of 404

[npeterson]

When viewing a page that doesn't exist, the template display is broken. It should be displaying a Page Doesn't Exists error. For example:

 http://www.plosone.org/static/tchecklist.action [^]

In the log:

2009-04-17 10:28:38,513 ERROR runtime(PLoSONE)> [TP-Processor155 freemarker.runtime] Error reading included file journals/plosone/static/tchecklist.ftl The problematic instruction:

---

==> include "${templateFile}" [on line 31, column 1 in templates/main_template.ftl]

---

Java backtrace for programmers:

---

freemarker.template.TemplateException?: Error reading included file journals/plosone/static/tchecklist.ftl

only happens for static actions

 http://www.plosone.org/tchecklist.action [^{] gives page not found}

probably related to the static action automation that dragisa added in, iirc, 0.9.1

we should return page not found if there's no matching freemarker template for a given action name.

(In [7615]) Fixes the pageNotFound issue introduced in r6553. Now if a page fails when being viewed under static content, we assume it's a 404 error. Freemarker offers no way to determine if a template exists or not. We may want to add a method to this in the action class eventually.

Verified that 404 is displayed for incorrect actions.
