Uize.Build.ModuleInfo really doesn't use the file system service directly anymore, so remove it as a dependency.
Using the slightly cleaner Uize.package format.
Some TODO doc tweaks.
Factored out the dependency tracing code from the Uize.Build.ModuleInfo module into the new Uize.Util.Dependencies modules, expressed in a generic form to allow it to be used for tracing dependencies for any kinds of items.
