Title: Add a way to set functions in the Sass_C_Function_List

This convenience method makes it easier to interface with the Sass_C_Function_List. By adding a function the implementing language doesn't have to figure out how index the List struct and add individual functions to the pointer array.

I used this to successfully execute Go code as a custom c_function, so awesome!
