Fixes Numerous market_hash_name Matching Issues

[Step7750]

This PR is related entirely to the code paths for converting market_hash_name to the 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

Thanks to #5 for the list of missing items.
