Various bugs on Rogue and 2 bugs on mobs

hansenmonk#5152

• Rogue; you cannot use bow until you learn a bow skill - [ranged basic attack] does not work.

• Rogue; certain effects do not seem to apply on skills learned.

• Rogue; when using [Caltrops] this effect happens -> Drop caltrop -> Jump back -> If attack move is used=move towards target. *In effect the "jump back" part gets nullified because you're forced forward when attacking afterwards.

• Enemy [projectiles] are "heatseeking", they follow the player and are inescapable unless you use [Dodge].

• Enemy [projectiles] can go through walls.
