mod_http_muc_log: Tweak style towards the "modern" Also accidentally converted the hand-minified CSS to SCSS for easier editing. This gets rid of the <q> element because it makes browsers (at least Firefox) add annoying quotes to any text copied out of them, interfering with opening non-linkified URLs. That could have been considered a sort of security mechanism, but convenience trumps security!

This module logs events where more than a certain amount of CPU time was
spent.

``` lua
log_cpu_threshold = 0.01 -- in seconds, so this is 10 milliseconds
```

Uses the Lua
[`os.clock()`](http://www.lua.org/manual/5.2/manual.html#pdf-os.clock)
function to estimate CPU usage.
