Add more items in the shop

[SebastienGllmt]

Some ideas:

• XP potion: gives some XP to a target monster
• Endurance potion: run for longer
• Temporary stat boost items (although they would have to be disabled for the arena/guilds/pvp)
• Stronger resurrection potion

An other idea :
item to carry 3-4 capture cards instead of 2 max : don't really impact tokenomics, usefull for players

[RadinEth]

• Monster encounter potion: Increase encounter rate in the wild for Xmins (useful to XP faster)
• Barter potion: Teleport to a barter's enclave ? (I think this one should be pricey, we don't want ppl to use them to rush faster to some locations and hunt rare+ as this is not intended to work like this)
