Projects merging and renaming

Here is another set of code updates understood as overall product refactoring. They were mostly driven by a company name change, but also include lots of changes indicated by ReSharper, Visual Studio's automatic analysis tools and my vision, how this all should go further. As a bonus, it also incorporates lots of bugfixes to the issues I found during testing.

Change log:
 * removed all old XAML UIs and view-models as they were already improved by me (i.e. debug-token window, signing window, update-manager window)
 * merged test projects into one
 * merged add-in project with the package
 * renamed the src/ folder into src_2010/, so all folders now look identical
 * moved files with similar purpose into a folder (like: Editors/ will now contain all classes responsible for working bar-descriptor editor)
 * renamed all the projects to follow new company name
 * renamed all namespaces to follow new company name
 * created new NativeCore project, that encapsulates only communication with BlackBerry NDK toolset (it doesn't provide any UI; the Package project is a layer between an NativeCore and VS UI now; this can be reused in future, in case other tools are required to build to help devs using pure MSBuild, also it speeds up testing)
 * fixed not working bar-descriptor editor in VS2013 (as wrong library was loaded on systems with VS2010,VS2012,VS2013 installed)
 * disabled scaling (stretching) of images in bar-descriptor editor, they now look much better
 * added option to disable optimized-deployment for a project
 * added tracking of NDK family (phone/tablet) and make the optimized-deployment disabled at runtime by default for PlayBook builds (so it's no more required to manually delete the app, before each upload)
 * removed the need of having Java installed to have the deployment/signing/packaging to work (build-tasks will now consume the Java delivered by the bbndk_vs itself)
 * MSBuild will now stop automatically at startup, when no installed NDK is detected with a respectful message (instead of failing a call to any BlackBerry tool with misleading info)
 * fixed MSBuild crashes caused by custom build-tasks crashing in logs writing code
 * latest installed NDK 10.0+ is automatically selected at plugin startup, if nothing selected before
 * fixed improper registration of BlackBerry debug-engine on x86 machines
 * fixed picked up location for bbt_id_rsa.pub by MSBuild custom tasks on Windows XP, as previously it was causing a failure, due to the whole folder non existence (now they share the location with Momentics)
 * and other small tweaks.
