- Autodetect SDK by environment variable EPOCROOT and qt directory
below.
- Environment::appendOrSet/prependOrSet: Avoid duplicate entries
- Rename toolchain enumeration value
- Adapt S60ToolChainMixin to new GnuPoc setup, provide routines for
  all required variables.
- RVCTToolChain: Make RVCT detection smarter (Check for RVCT<v1><v2>BIN
  variable). Set all required variables in case of RVCTToolChain/GnuPoc
- QtVersionManager: Detect toolchain and Qt version properly, make S60
  device run config accept toolchain.
- Modify S60DeviceRunControl to execute 'make sis'
- Modify S60Devices::detectQt...() to check for Qt installed into SDK
  first and symlink as fallback.

Change it into a singleton that listens for device changes
and emits signals when devices are added or removed.

Factor out the initialization setting up the environment and headers in
the RVCT/GCCE toolchains.
Modify the RunControl to be able to support different package
building/signing processes.

creating a debug run configuration. Import the debugger
into Qt4ProjectManager.

and ApplicationRunConfiguration to LocalApplicationRunConfiguration,
preparing remote debugging. Change the interface canRun() to be const,
run() to create() (since it does not run anything), use references
to the QSharedPointer<Foo>. Introduce d-Pointer and remove
unneeded headers from ProjectExplorerPlugin and add missing includes
everywhere.

It works, except that the code model doesn't get the rvct include
directories and defines yet. And you need to have everything for
rvct set up in your environment.

And adapt the device selection list.

The runner uses the applicationlauncher internally, which is now
exported from the projectexplorer plugin for that reason.

At the moment you need to close and reopen the preferences dialog though.
