Progress may halt at two mods left

How we got here: choosing "banner text" as the problematic mod in whatever version of polymania I'm testing with. What seems to be happening is Banner Text is being chosen first - it has the least dependencies, due to the program counting deps of deps, even if those deps are provided in their parent. It depends on a module of FAPI, so FAPI is enabled. Hopefully this kind of thing is reduced by this fix, but a band-aid might be applied by checking if the previous list == this list, indicating that something went wrong (see #14).

Update: After fixing deps of deps that are parents or siblings being counted, it still happens. What needs to happen is if all mods are added to the testing set, we need to put them back in the candidate set, remove them from the testing set, and rotate the order they're in, then try again.
