Relics and More

I have implemented Relics into Spellrow now, and the trade event to find them.

Relics are items which affect gameplay in different ways, as a simple example: Sand Paper: When a mark the owner does not control is moved, it's power is reduced by 1. 

This greatly expands your deckbuilding capabilities, and adds avenues for me to make even sillier additions to this game in the future. Still I do understand the need and value for simpler relics so don't fret too much :P
The trade event in which you can attain relics from uses your own deck to trade with. You can trade your marks for new ones and relics.
Each opponent now has a unique background visual to match their theme.

This update also adds, reworks, and rebalances some marks, most of these changes being buffs so I'll leave that to you to find.

Have fun ^^
