Fix/optimize CoC ID filters

[Technus]

Description.

Using localized resources is nearly impossible due to improper CoC ID filtering.

Motivation and Context.

Allows to translate compendiums in a working way.

Some resources are being removed from index by: CoCID.filterAllCoCID (documents, langFallback)
which causes the game to be partially localized.

ex. Credit rating - In my world/module there is a valid translation + valid skill with higher priority, yet it is not used.

• CoCID.filterBestCoCID(documents)
  • Added defaults for priority parsing
  • Added local caching of current document
  • Moved check if document is already present to top, and if not to add it without any preference checks
• CoCID.filterAllCoCID (documents, langFallback)
  • Added defaults for priority parsing
  • Added local caching of current document
  • Added sorting of eras before creating 'eras used identifier'
  • Moved check if document is already present to top, and if not to add it without any preference checks
  • Now correctly supports Priority system
