Modify Guarana usability

Hello! I don't have much to say other than I think guarana needs to be modified a bit in order to use it more easily. Right now you can't use guarana if your wolf has 20% energy. I understand having a limit of energy may be there to prevent using one on a wolf with a lot of energy, but I have experienced some problem with this low limit.

I scout my wolves very frequently, I use guarana to send them right back out as waiting for them to reach max energy takes way too long. Its a bit frustrating when I come back a bit later than usual to collect them and they are at 20%, making guarana unusable on them, and making them unable to scout until they get to 100%. I think the bar should be raised to 60% or 50% at the lowest. 

Its especially hard for scouts to get rid of energy if they aren't at a point they can scout or rescout, unlike hunters and herbalist that take 20% each time they do something. So very easily you become stuck unable to use the guarana since you can't get rid of their low energy and are forced to wait.

I don't really see the downside of this. Sure, some players may "lose" some of the energy if they use it at a higher number - say we make the limit 50% - but that won't really change the balance of the game.

Maybe you could make guaranas 10 uses, each use giving 10%? I don't see much of a problem with this and it would solve the issue.
