Feature Requests: Floating Mana and Custom Mana Values.

This is one feature request for the playtester and one for the deckbuilder (and maybe I've missed how to do this, but I couldn't find it after a little fiddling).

Firstly, in the deckbuilder: an option to set a custom mana value for cards, for example "Of One Mind" often plays more like a 1 drop, rather than the 3 mana value card it actually is, and when viewing the mana curve of my deck it would be useful to be able to override what the program thinks the card costs.

Secondly, in the playtester: Some trackers for floating mana, at present I just use a treasure token with a sticker but something a little more 'fancy' would be nice.
