qmake should append user grantable NetworkServices capability to mmp files generated for Symbian projects

Getting started with Qt tutorial in Symbian.org website* instructs developers targeting Symbian devices to "add the NetworkServices capability to your .pro file and increase the EPOCHEAPSIZE: 0×020000 0×4000000", both settings which are magic to people with no previous Symbian background.

Almost all modern, non-trivial Qt applications require network access, so the (user grantable) NetworkServices capability should be added to all Qt projects implicitly. Otherwise many developers will stumble on this Symbian special case needlessly, and waste hours learning what went wrong. For people with no Symbian background, it's difficult to know what Symbian-specific flags (that has no equivalent on other environments) you need to add to make your application actually run successfully on a device. If the network capability cannot be added to all projects, at least the ones with lines "Qt += webkit" (web UI) or "Qt += declarative" (network transparent fuild UI applications) should automatically have one as they often require networking.
