This could be made even simpler by not using a LESS varialbe for
hacks.less, but loading it conditionally through the moduel def.
But, as a first step we can merge the two as-is.
Given that the subject and target are always referenced together
in page views, there is no need to keep an alias around. However,
I'm keeping it anyway so as to not produce any
`/* {"skins.foo":"missing"} */` appendix to the stylesheet response
for these cached URLs.

All stylesheet-only ResourceLoader modules now have a single entry point
rather than multiple files. This eases compilation of the content of
those modules by all toolchains, which will be useful when introducing
the bundlesize tool.
