Few things here and there

- Card management, you can now modify the name of the cards and remove cards too.
- Also, support for multiple cards with the same ID works too. When scanning for the first time, if a repeat card exists, the user will be asked to choose which card the character comes from. Future scans will not ask since it is stored in the watch app reserved area.
