Set level of sword that can break pots

[puddydoo]

What feature do you want to get added? And how it will work?

The existing option makes it so that the level 2-4 sword can break pots when set to 1. However, this is inaccurate to the GBA version, where only the level 4 sword can break pots.
It should be changed so that the setting dictates the minimum level of sword that can break pots (while 0 disables it). While noting in the comment that setting it to 4 matches the GBA version.
