Improve UX when specifying card set on session creation

[PolygeneLubricants]

The current UI is not very elegant when creating a new session, and specifying cards.
I propose the following changes:

• Add cards in a multi-select input field, so space creates an option, instead of a raw comma separated list. Example:
  
• Add presets with common alternatives to the default planning poker card set, like Fibonacci, T-shirts.
• Save the last chosen card set in local storage, for the given user.
