BlackBerryConfiguration class has been rewritten to generate kit,
qtversion, toolchain and debugger for each available
<QtVersion,Architecture> pair.

This allows to use proper debug symbols i.e. target/qnx6/x86 for Simulator.

All kits, qtversions, toolchains and debuggers are claimed to be
autodetected.

Note it still requires to have matching version of the BB NDK Target and
simulator/device OS Image for proper debugging.
