Currently if user is behind a proxy server and want to set it up correctly
then he has to do it on 2 places:
 - for the IDE using Tools->options (for eg. autoupdate)
 - for the server - start server, go to runtime tab -> AS -> JVM options, set it
and restart the server.

   It would be better to start server with proxy JVM options defined in the IDE.
It would be very useful for users working with webservices mainly in cases they
are working with local and remote webservices at once.
   User should be also able to don't use these pre-defined values, so for this
case i would recommend to add new option to Tools->Options->Advanced
Options->IDE conf...->...->SJSAS, eg. "Use IDE's proxy settings" with chechbox
which would be checked by default

   This applies to following options:
http.proxyHost, http.proxyPort, http.nonProxyHosts, https.proxyHost, https.proxyPort

   Plugin should get correct values of these options for the server using
"System.getProperty(propName);".
