Automatic update is now working.

The Update check and download URL are fully configurable from the settings file, so if for some reason, my host dies, or should someone choose, the update can be fetched from an alternative URL.

Further changes which are currently under way – checking on the argc and argv parameters in main to determine if the path to the DOL has been passed. If not, then relative addressing as used previously is still used. This will probably need a hard coded path to make it work with other loaders (other than the HBC). This will be a future change.
