Reformat ALL the source!

Reformat ALL the source!

Yes, yes. After stubborningly refusing to switch to a more readable coding style for
years, I finally give in. Our old, quite compact, 2-indent style was born from my time
with homecomputers, where every whitespace was a waste. Later (and mostly thanks to EgS),
I did see the light, e.g. changed from one-letter variable names to useful ones, but
still shied away from reformatting the whole source, touching every line, destroying the
historical context as shown by svn and git blame.

However, since I'm now doing Qt-related programming as my day job, and use a proper
(Qt-like) coding style there, it has become increasingly annoying for myself to switch to
another style in those long hacking nights working on Quassel, and so I decided to
Just Do It™. Helps that Git nowadays can ignore whitespace changes when blaming, or
diffing, or patching, so this shouldn't be too much of an annoyance for existing patches.
Feedback from the community was also positive...

So now we use a style that should be pretty close to the Qt Coding Style [1], which not
only covers the indentation, but also things like newline-after-function-head.

Reformatting was done automagically using uncrustify [2], a script and config file is in
scripts/manage/. Please don't run it over the whole codebase again, as there are some
false positives and weird formattings that will have to be manually fixed over time.
You can use it for reformatting existing patches or MRs, though.
