This will help us deal with shader name collision. Breaks the Windows
build for the moment, unfortunately.

This allows actors to perform draw commands in TickDraw(), even
if it’s not exactly what we want in the future.

For now the flags are: --disable-doc --disable-test
--disable-samples --disable-tutorial.

All these changes will allow us to more easily add Lol Engine as a
submodule of another Git project.

- removed 0 CR characters
 - removed 1 trailing whitespaces
 - replaced 1 tabs with spaces
 - fixed 367 svn:eol-style properties

Not all programs support this feature for now, but that’s because they
don’t support the scene framework either, and will need patching. Also
the default postprocess is deliberately exaggerated for now.

Now TickDraw() can be called several times per frame, because we
may have several scenes. This is expected, but it will require
some adjustments later.

Add String.split(char) to split into an array, and add a simple
char const * + lol::String free operator.
