Missing math.pow

[Arnaz87]

The function math.pow is missing, math and all the other functions are there but not pow

[poga]

Lua 5.3 deprecated and removed math.pow, use x^y instead.

[Arnaz87]

oh right, but my local lua 5.3.5 installation still has that function

[Arnaz87]

You are right, math.pow is not in the documentation anymore, maybe someone forgot to remove it in my version

[FreeMasen]

deprecation and removal are not entirely the same. It would be nice to have the ability to build the embedded Lua with LUA_COMPAT_MATHLIB, to allow for usage of deprecated math functions as they would be provided by a default installation of the language.

I agree it sounds reasonable to be able to configure the Lua library used. Maybe this can come out of the work on #191 .

While I understand the desire to batch this change with another version of rlua, I was hoping this would be available with lua 5.3 since a consumer moving from 5.3 -> 5.4 is more than just dealing with this difference.
