Missing Content-Type headers

[prateepb]

Servlets need Content-Type: text/html header please:

[root@centos ~]# curl -v  http://localhost:8080/spiracle/Get_int?id=1
* About to connect() to localhost port 8080 (#0)
*   Trying ::1... connected

This appears to be because we do a lot of manual writing to the response objects output stream and not to a nice presentation layer JSP. Because there is no file system entry for the actual response tomcat doesn't appear to be setting the mime type.
I think I can put together a hack by manually setting the content type header in the SelectUtil.java and UpdateUtil.java but the real fix is a proper MVC pattern for the whole SQL injection side of things. One is quick and hacky the other is a more fundamental change to the way the app presents data and is more in line with how the other servlets go about it.
