Merchant Scaling Fixes and Tweaks

Some edits to how merchants scale their stock.

The main download contains 4 major changes to the original script:

--Staves are included in the list of scalable item types

--a faulty check for store level override has been fixed (used by only three stores - Ilen, Ademaro, & Levi)

--the main RNG component (adding or subtracting up to 3 from effective player level) has been removed

--all stores add rune slots if the item is high level enough (instead of a 0-25% chance)

Because stores are now guaranteed to be at player level or slightly above, and everything has rune slots, be warned that this may make buying things more expensive.

Limitations:

--Not every item is set to scale by its material progression.  Unfortunately, there is no scripting function to change this; it has to be done by UTI edits (many can be found in the optional & miscellaneous files here, with more item mods are listed in the description page).

--Runes prevent items from scaling!  To scale items by selling them to a merchant and then buying them back, you must remove runes first.  ("runscript zz_upgrade" if you don't want to find your way back to Sandal 😉)

If you want to see how the store scaling originally worked and my notes / changes, check out the Articles tab.

Miscellaneous:  A script to fix Levi and Mikhael's stores--both contain an error that guarantees higher-tier items and rune slots.  Separate and optional because it's a pretty useful error. 😆  It's a script that runs the first time you visit the repaired version of Soldier's Peak, to avoid conflicts with mods that edit their store inventories.

Alternate versions under "Optional":

--Original rune slots mechanic

--Original RNG mechanic (includes the possibility for items to scale down)

--Fixes only (includes the possibility for items to scale down)

Conflicts:

Will conflict with any other mods that edit gen00pt_generic_actions.ncs, although I'm unaware of any.  Additionally, some stores are special and use different plot scripts to open.  I've also edited all of those scripts I could find (see readme for scripts and affected stores), but this does mean a lot more potential for mod conflicts. Best delete the conflicting script from this mod if that happens.

Patch for Qwinn's Fixpack is included, since it's pretty widely used.

Since I've only edited scripts, this should be completely compatible with mods that change merchant inventories and/or add new merchants (although if the added merchant uses a custom script to open, it won't be affected).
