Unified the page-counters before.
This makes processing of counters in javascript way more easier. The minimum
required browser versions for the needed CSS3 selectors are IE9, Firefox 3.5
and Chrome 5. Confirmed working with IE9, Firefox 24.6, Chrome 36, Mobile Safari
on iOS6.
An unintended side effect of CSS brackets is that theme designers are able to
implement there idea of brackets.
Pressing the question-mark key (?) produces a pop-up listing the
keyboard shortcuts. Pressing q whilst this window has focus closes it.
I've provided crude translations for the additional ? and q shortcuts,
obtained from Google Translate, but they should be checked by native
speakers.
