Restoration Spell Fix

Intro
Think about Showtime's Magician Career. Done? Good.
Now forget it because that has nothing to do with this mod.

Mod Info
Developed and tested with game version 1.67.
Requires Supernatural EP (it's useless otherwise).

Mod Description
The screenshot is pretty self-explanatory, but here's the description anyway.
There's a check missing in the code of the Restoration spell, so, when casted
successfully, it affects also unspoiled food stored in a fridge with 2 virtually bad consequences:
- set quality to Neutral (maybe it was better than that)
- update the spoilage timer (maybe the timer was greater than 10 hours, the default value)

This mod fixes that so only the spoiled food in the fridge is affected by the spell
(like already happens correctly for food outside the fridge).

Compatibility
This is compatible with xml and ITUN override mods (presuming they exist) that tweak
that spell/interaction or those that tweak wands.

Special thanks
I'd like to thank icarus_allsorts for technical help (compatibility with ITUN mods).
