This class will be used to push queue changes directly to the GUI.
Currently changes get mapped through the old callbacks system, which can
lead to several inefficiencies because the GUI has to look up each queue
structure in a list.
This patch implements a basic QNotifier class and provides a function
for setting a Queue's notifier.

This function converts unsigned ints into strings. This allows me to
replace several almost identical functions with one function call.

I provide an accessor function to keep this value from ever getting
changed outside of the Track class.

This variable should only be set by the Database when a DatabaseItem is
first created. This means I should hide _index from the rest of the
world to prevent accidental modifications. I also add an accessor
function for other code that needs to read _index.

I now mimic the effects of the "changed" callback with inheritance.
This makes for a cleaner implementation.

I plan to introduce a new lib/ that sits between the gui and the backend
files (similar to how glibc sits between the kernel and userspace).
This gets the rename out of the way before I change my mind again.
