Metamethods for dividing a Vector and getting the reciprocal Vector

[Chr1Z93]

Example:

local vec = Vector(3, 2, 1)
local half = vec / 2 -- (1.5, 1, 0.5)
local reciprocal = vec:reciprocal() -- (0.33333, 0.5, 1)

reopening @zerothi's comment, it would be best to either

• permit number / Vector (given that we're already applying componentwise operations, this would be well defined as Vector(n / x, n / y, n / z))
• or hard-error deny number / Vector operations

rather than silently failing with a nil

reopening @zerothi's comment, it would be best to either

* permit `number / Vector` (given that we're already applying componentwise operations, this would be well defined as `Vector(n / x, n / y, n / z)`)

* or hard-error deny `number / Vector` operations

rather than silently failing with a nil

Updated it so that vector / vector and vector / number are handled.
