Improved surface gathering

[Serula 105]

I'll keep it short and simple. 

- Surface rock gathering should not have a delay. You should instantly pick up rocks so it becomes more of a skill to gather them fast or seek out the T2 rocks rather than the waiting game it is now. Just give less resources per rock.
- It will be more interactive and less tedious because you are more active and constantly pressing buttons.
- The walking or running talent will play a more interesting role because you can get to the next rock faster.
