Small polishing of the previous commit + Item Sorting

- Fixes a few bugs from the last commit, namely:
     - The guy who gives you the Pocket Lapras having bugged text
     - Being able to use it where you shouldn't (Cycling Road, Seafoam before the boulder puzzle)
     - Pocket Lapras not having an item description

- As well as this, automatic item sorting has been added. Just press Start in the bag menu and all your items will get assorted into a convenient list.

- Changed a few item descriptions since some of them didn't terminate properly

- Freed up some space in the Home bank
