* Move method to SkinMinerva
* Turn preparePageContent into a getter that returns the subject
page
* Use getSubjectPage in template
For mobile special pages this now means the page has two .content elements
On those pages I've disabled the initial content element. It also means
various .content <heading> and .content ul rules now apply that need to be
disabled.
While testing several other issues were taken care of - for example
the h2 in errors

Content using `header` as a CSS class was affected by skin styles
in Minerva being insufficiently specific to the skin‑specific elements.
This changes Minerva to use `class="minerva‑header"`, thus avoiding
the conflict and matching what Vector does.

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.
