Created a new Uize.Build.Test build script module to replace the old Uize.Build.RunUnitTest and Uize.Build.RunUnitTests modules. The new module has a simplified params interface (eg. node build.js Uize.Build.Test module=Uize.Data.Diff).
Factored out the test running logic into a separate Uize.Test.Runner module, so that it can be shared by the UIZE unit tests page of the UIZE site.
