Summary:
File path character limit blocks HD resource packs

Impact:
Prevents HD texture packs from passing validation

Repro Steps:

     1. Create an HD resource pack with a name longer than a few characters long
     2. Create a subpacks route to allow multiple resolutions
     3. Attempt to validate

Observed Results:
Validation fails due to character limit in file path exceeding 76 characters

Expected Result:
Passing validation due to no actual errors in the pack.
