The QRC file is a platform independant way of referring to resource
files. It allows the program to access resources in an abstract way
instead of the direct file path.
This is the first step towards moving all files to the new system.
Elements work like they've always done, this just moves the commonly
used components away from the global namespace.
The qmldir file still does something, although at this point it is
unknown exactly how it's used and whether or not it could be changed to
simplify imports across the block.
