fixed errors in death hook and some other optimizations

fixed constant errors when dead

fixed errors when the player isn't authed (shouldn't happen, but whatever)

base_gmodentity -> base_anim

base_entity -> base_gmodentity

Fixed fish and lure collision, and errors when a player disconnects.

Minor cosmetic update, forgot to reset the texture so sometimes the circle could draw with a texture. Also reset fish angles when respawning.

Added a confirmation button to selling fish, added an inspect button under the sell button, made the lure display price when hovered instead of all the time.

Fixed singleplayer errors.

Hotfix fish being picked up by gravgun.
