[Building Sakai] Tool placement id

[Mark Norton]

Depending on what you're trying to accomplish, a servlet may not even 
need a placement.  If the servlet is a REST processor, for example, it 
doesn't need to be registered as a Sakai tool and have a placement.  
OTOH, if the servlet is generating a UI in response to requests and 
needs to be visible in the Sakai portal, then it will need a tool id and 
placement.  For example of a REST handler with no tool id that runs in 
Sakai, see https://source.sakaiproject.org/contrib/softchalk/trunk.
