Use setPos/setAng directly on the entity instead of phys

[wrefgtzweve]

This pr makes it so E2 setPos and setAng are called on entities instead of their physics objects. Also fixes some linting issues in the file.

Example of previous weird behaviour:

local P = vec( random(1,100), random(1,100),random(1,100))
entity():setPos( P )
print( entity():pos(), "|", P )

New behaviour:

The same applies for setAng:

local P = ang(vec( random(1,100), random(1,100),random(1,100)))
entity():setAng( P )
print( entity():angles(), "|", P )

Previous: New:

This also makes setPos and setAng no longer weirdly lerped and actually makes them properly snap in place. Before the PR:

If needed i can fix the linting errors in the file
