Sort out requirejs paths...
so modules get loaded properly from tests & main code.

+ by default, the base url for resolving dependencies is the folder of the main file specified in data-main ('js' in my case)

+ So, paths in the actual code should be specified relative to this...which usually means they don't need a path as most of my JavaScript will be in this folder. Nice :-)

+ I need to specify a baseUrl configuration option for the tests so that it will resolve the paths in the actual code to the same location (baseUrl: 'js' in my case)

+ So, paths in the tests should be specified from this base also.
