syllabus.read events only recorded for maintain role

Currently, only the maintain role is able to to invoke the syllabus.read event.
Only the maintain role can see the following link in main_edit.jsp, hence invoke processListRead and log the syllabus.read event.

<h:commandLink action="#

{eachEntry.processListRead}

" title="#

{msgs.goToItem}

#

{eachEntry.entry.title}">
<h:outputText value="#{eachEntry.entry.title}

"/>
</h:commandLink>

FIX: All roles should also invoke the syallbus.read event, so that it is clear who is reading the syllabus.
