Explicitly reference the loader

[guusdk]

By using the short name for a loader, another node module that matches the loader shortname might be used, giving weird errors. This is prevented by referencing the loader by its full name (by adding '-loader' to most short names).

This prevents errors like these:

/vagrant/node_modules/loader-runner/lib/loadLoader.js:35
                        throw new Error("Module '" + loader.path + "' is not a loader (must have normal or pitch function)");
                        ^

Error: Module '/vagrant/node_modules/url/url.js' is not a loader (must have normal or pitch function)
