Move all the things (YES. Move them.)

Also, implemented some basic modlist logic, to be wired up.

+/**
+* This class is modelled after QDir, and is designed to provide similar
+* features for ZIP archives.
+*
+* The only significant difference from QDir is that the root path is not
+* '/', but an empty string since that's how the file paths are stored in
+* the archive. However, QuaZipDir understands the paths starting with
+* '/'. It is important in a few places:
+*
+* - In the cd() function.
+* - In the constructor.
+* - In the exists() function.
+*
+* Note that since ZIP uses '/' on all platforms, the '\' separator is
+* not supported.
