minor cleanups, mostly in own code

* fixing my hat preview bug nemo pointed out (thanks!) + cleanup of edit page loading, should speeed up application startup a bit.

improve and cash hilight regexp

highlight improvements * only highlight if surrounded by whitespaces (or trailing ': ') + case-insensitive

oops

Case-insensitive comparison of nicks

potential fix for issue #217 (SigSegV while in game room in KillAllTeams - team list change?)

retain dx/dy from landgun

doxygen seems to get confused if a ///< line is followed by a /// line

* adding destructors to my line edit subclasses + case-insensitive sorting for suggested nicknames

let's create some templates so that the user knows how to start off

document css files better

Tweak ratios to deemphasise foreground flakes further

minor signal fail fix

some more chat fixes and changes, I think. hum. what was that? um. aaah, I better go catch some sheep ... er sleep.. um..

ugh wth... cleaned FL/IL change notifications up

some changes to the css... display:none; works now (e.g. you can use it for user join/leave messages that are not your friends)

Bit of an experiment with giving flakes a bit more depth. Might need to be theme flagged, or theme flakes reworked on some themes. Looks neat in stereo. Also finally use an array for the layers

BOOOOooOM <headshot>! removing default stylesheets from c++ code and adding them as text files to the qt resources

same for chat. changed the paths to: css/qt.css css/chat.css note: display:none is not supported by QTextBrowser, I might pimp it up to do so

frontend will use the data file misc/qt_style.css instead of hardcoded stylesheet - if the file exists

moving a file around, fixing a png, etc.
