Added project-item template of empty makefile
Updated release-notes to match VS-Gallery pages
Fixed description of OpenGL v1.1 template project
Improved merging MSBuild/project property values

They look more 'natural', when browsing settings.
Removed from bar-descriptor unsupported build type
Added template for Qt4-app for PlayBook & BB10

Requires drop of Qt4 libraries (build by me) into the project's folder.
Somehow the standard ones from NDK doesn't load correctly.
