v0.12b: random hotfixes

once again too lazy so here's the info

• bug count in dark knight land has been basically halved and moved around
• bug health has been reduced
• top of cave has been elevated to prevent bugs from agroing through the walls
• minor dialogue changes to places that steg hasnt been yet
• swing hitbox has been changed to a large box in front of you instead of the visual strike

to add:

• agro check for line of sight
• set up scripts in prep for de-agroing
• complexify movement script so force is applied only in two dimensions
