Changed default binary output path pattern.
Ignore common build and new binaries output paths.
Added support for content collecting.
Added rules to copy platform-dependent files to runtime output path.
Better support for IDE-based builds.
Fixed ColladaConv default out/base paths.
Binaries folder is now created inside build path (out-of-source build).
Revert deletion of "extractAppPath" helper function from samples.
Fix content folder location on MacOSX. Exit samples if resources can't be found.

All the code to locate the resource folder `Content` is isolated inside the `extractResourcePath`.
When the samples can't load the resources, they are stoped instead of showing a window with flickering garbage.
Fixed resource logic on Linux.
