Playing Card API bug fixes

[Aurelius7309]

Fixes:

• Fix a bug with get_straight deviating from the base game's behavior, not allowing five card straights with four fingers
• Fix an issue with is_face not accounting for stone cards properly, causing stone cards that were face cards originally to be considered face cards
• Address an issue where added playing cards are unloaded on profile/language change.

Known issues:

• The playing card API currently does not offer multi-language support, and any information inserted regarding new playing cards is erased when changing languages. This will be implemented at a later date.

New commit fixes an issue with cards not being reachable starting from Aces in get_straight. Also I removed the upper card limits in get_flush and get_straight, as this is an irrelevant case in the base game, and removing it allows mods to check if the entirety of cards held in hand can make specific hands.
