Fixed #943 (Creating new applications without altering web.xml)

Fixed #943 (Creating new applications without altering web.xml)

How to use
 * Try http://localhost:8080/myContext/run/com.itmill.toolkit.demo.Calc

web.xml contains run/* servlet with applicationRunner=true parameter.
This should not affect Toolkit in any way if applicationRunner is not defined.
Currently it is defined only with run/*

This needs review. Reason why I did this is to
 * skip one step more for newbies
 * "how to start" flash demo is simpler (included XML is enough for any new application)

Side-effects
 * UIDL request have part of URI path after their UIDL request, see firebug
