refactor UpdateKey parsing, move responsibility for subkey matching

UpdateKey parsing now allows multiple : and @ inside the update key,
splitting on the first occurence of each

Subkey matching is moved into IModDownload / GenericModDownload, in
preparation for some Mod Sites using something less error-prone than
substring matching.
