Flamethrowers that can be angled at 45 degrees

[1WheelDude]

The other day I attempted to build a defensive wall at a 45 degree angle. Things started to look good before I forgot that flamethrowers only rotate in 90 degree turns. This made positioning of the flamethrowers difficult without causing potential damage to other turrets along the line, and just made the position of the flamethrowers look really awkward along the 45 degree wall.

Would like the ability to allow flamethrowers more granularity with its rotation.
