* add reset power and toughness function on cards
Add actResetPT to set the power and toughness in the same way as
actSetPT but instead of prompting the user it will fetch the original
pt from the card info for each card.
Add the new command to the card rmb list, keybinds and settings.
* changed style to .clang-format
Please change the contributing guidelines to use this style instead.
