Improved item purchasing system to sell items when inventory is full

[JoshdanG]

Improves selling when inventory full:

• larger list of items sold
• sells one item at a time
• sells regardless of time or level
• avoids selling parts of a recipe in progress
• only sells items in inventory (not stash)
• considers full with 9 items rather than 8
• only sells within valid range (450) of fountain

Performance changes (unmeasured):

• checks only when possible to sell
• waits one second before re-checking

Removes .mira file that complicated things with limited benefit

[JoshdanG]

I wanted to ask if it would be okay to remove the ItemPurchaseSystem.mira file and just work directly with the .lua file. This is much simpler for testing, code tools, etc. and the benefits of .mira seem very minor.

If so, there are some comments that should probably be brought over.

If not, then I will edit the .mira file and compile to .lua.

@JoshdanG Sure, you could remove the mira files. Currently, we are not using mira complier.

Thanks for your work.
