Add clicking and fishing API

[FliegendeWurst]

Also fixes a bunch of warnings. Let me know if I should change something :)

Tell me more about the use cases for the clicking and fishing.

[FliegendeWurst]

For example, you could create an automatic fishing bot:

while True:
    mc.player.clickRight()
    mc.player.pollFish()
    mc.player.clickRight()

I prefer the stdout logging method: it nicely integrates into the Forge logs.
