Deck preview and tooltips!

Hello everyone!
This is just a quick update, no major gameplay updates just some new needed features and some bugfixes.

Keywords now have tooltips! no more trying to remember what they do.

Deck preview! Now you can look at all the cards on your deck at any time from a button on the top right of the screen. There might be bugs here.

Boss icon on the map added! Now, after finding the key, the gate node will change into an enemy icon. No more boss jumpscare here.

Fixed a bug where some text where to long for the text box.
Fixed a bug where the attack button could get stuck at a random size.
Added some small feedback when you are out of mana and you are unable to play a card.
Changed the mana and attack button closer to the cards in hand.
Changed the size of the life amount for better readability. 
Fixed a few typos.
