Improved Item Name Matching

This release includes significant improvements and fixes when converting a market_hash_name to it's corresponding image URL.

Fixes:

• Conflicting case sensitive weapon language references
• Item name simplification/extraction and trimming
• Duplicate match handling for skin names, weapon names, paint indexes
• Ensures weapon tags are lowercase
• Improves Robustness of weapon checking from market_hash_name by attempting to find the weapon instead of checking for wear
• Searches prefabs in the case of no match for "other" items
• Vanilla item support

It also now allows just specifying the item name without the wear (ex. AWP | Redline).

Thanks to @jayjo29 for the missing items list
