[ANN] AppBundler.jl - Bundle Your Julia GUI Application

@Janis_Erdmanis Following our earlier private discussion, I would be interested in using AppBundler in conjunction with JuliaC to create Windows/Mac shared libraries that can be loaded from a C binary.

These should respect each platform’s rules w.r.t. bundling, RPATHs and so on. I can provide a Mac signature to test codesigning.
