Corrade.

Newlines at EOL.
Mention in README that we have now 10 playable and one brainfuck level.
Set projection matrix once and for all.
Position the light above center of the level.

Makes huge levels less dark (but proper multi-light setup would be good
to have anyway).
Special frustrating "winner" level for those who make it to the end.
I like this version better (more frustration, yeah!).
Reorder the levels a bit.

The upgraded one is now the hardest of the easiest.
Adapted to Magnum changes (mainly convenience shortcuts).
Another player movement rework.

Now it is finally with less `friend` declarations and no weird private
access.
Updated FindCorrade.cmake from Corrade repository.
Updated FindMagnum.cmake from Magnum repository.
Added "just-to-be-sure" assert.
Getter function for remaining targets.
One more sanity check.
Code cleanup.
Added Timeline.

Will be used for animations and stuff.
