AR-15 description update
Merge remote-tracking branch 'origin/master' into wheelJack
Made no jack same as is wrenchable for removal. Made is wrenchable
higher priority over is wheel.
Made smaller wheels wrenchable
Gives SWAT armor a slight boost.

It's uncraftable and quite encumbering, and research indicates that SWAT
armor is typically NIJ level III or higher.
Merge branch 'swatboost' of https://github.com/Rivet-the-Zombie/Cataclysm-DDA into merge3
Adds 4 environmental protection to the SWAT armor.
Slight steel-toe boots nerf.

This leaves them with double the protection of vanilla 'boots', but
makes them slightly less superior to, well, EVERYTHING like they were
before.

Slight steel-toe boots nerf.
Use map::ter_at/furn_at to get terrain/furniture

They return the terrain furniture object directly.
Editmap: swap items vector and cosmetics map instead of memcpy.

memcpy leads to memory leaks in the overwritten vector,
swap is faster than assignment.
Apply astyle to some map functions
Make the vehicle cache map use a point instead of a pair of ints.

Because it's not some arbitrary pair of ints, it's a point.

Replace some manual checks with inbounds function, the checks were wrong
anyway as they did not include the lower end (x==0 or y==0).
Add functions to access contents of map::grid

Use those function whenever the grid was accessed.
Always use the get_nonant function to calculate the index of the
requested submap. Do not calculate the nonant directly.

Use range based loops for accessing map::grid.
Fix map rotation code:

Now also rotates fields, all members of the cosmetics map and radiation.
Bypasses all map limitations by swapping the submap directly.
