Forest cleanup

• Remove duplicate eventpool events.
• Fix indentation.
• Name all inline events.
• Fix tree root assault to respect $plantdisable, under the same check as forestplant_kiss and forestplant_snare.
• Extract repeated forest_wolf code to a widget.
• Pull mushrooms out of the event pool and give a fixed drop chance.
• Change weights to ints to make calculating odds easier.
• Make bee event always happen, just maybe without bees, so changing toggles won't affect drop rates.
• Move duplicate hunt-starting code into a widget.
• Move hunt start call outside eventpool to a constant trigger rate.
• Remove unneeded $rnd2 var.
• Moved duplicate code out of the elseif ladder in :: Forest.
• Set probabilities of hunt starting to be 1:12 in eventforest, 1:6 in eventforestdeep. This is opposite of previous, and when searching at max allure, gives a 5% and 10% chance of hunt starting, respectively.
