Built and installed the SIP Development support plugin. It is now possible to
create a converged SIP/HTTP project. I added one.
Next step is to add SIP servlets and SIP Listeners to my project. This can
easily be done by rightclicking on the new project and selecting "New" -> "SIP
Servlet..." or "New" -> "SIP Listener...". A wizard will start up guiding me
trough some steps, nicely ending in skeleton code.
When selecting "New" -> "Other...", however, a "New File" dialog pops up. The
SIP Servlet and SIP Listener are not listed in this dialog.
