web: Add missing PHP global statement so the refresh_interval config option works
valen: Record response time for monolithic facilities too
web: CSS cleanup
web: Remove unused CSS rule
web: New facility instance status display format replacing traffic lights
web: Remove last traces of the traffic light visualization scheme
web: Use isset() conditionals or ignore array key nonexistence notices
web: Fix for IE 6 not unsetting bullet list images with list-style:none
web: Remove superfluous CSS rule which IE 6 doesn't understand anyway
web: Simplify rule so that IE 6 can parse it

There aren't more than one <span> children of the facility description
<div>, anyway.
web: Reduce padding around the instance status labels (inc. row start)
web: Add engraving effect to facility names
web: Add background color transition effect to facility blocks
web: Display response times as tooltips of facility/instance status labels

Definitely not the best approach for this, but it'll do in the meantime
until the front-end gains more features such as detail subpages, graphs,
and stuff.
web: Replace #visualClear elements from MW with valen's own .fc
web: Remove final ?> from common.php
web: Use a minimal version of Glamdrol for a base CSS stylesheet

Compared to glamdrol/main.css which has 1184 lines and is 16.5 KiB in
size, glamdrol/mini.css has 329 lines in 4.3 KiB. It only contains the
styles I deemed relevant for generic pages, without all the
MediaWiki-sepcific cruft normally needed for the wesnoth.org proper.

With this change, the original big Glamdrol stylesheet is no longer
required, so it's now gone.
web: Adjust refresh countdown JS logic for clearer results

 * Always include the 'N seconds' bit, even when the seconds portion of
   the countdown is zero.
 * Don't include the 'N minutes' bit when the countdown is below 60
   seconds.
 * Use '1 minute' instead of '1 minutes'.
 * We still use '1 seconds', though, because the transition between '2
   seconds', '1 second', and '0 seconds' doesn't look nice.
web: Make all status indicators inline blocks with centered text

Contrary to my previous impression, IE 6 actually seems to know the
inline-block display mode...
web: Use more uniform dimensions for status indicators

The previous commit making the header indicators inline blocks messed up
the dimensions slightly due to the model change, so we may as well take
this opportunity to fix that _and_ make indicators use a minimum width
(specific to indicators of the same class) for a more uniform and clean
appearance.
