Returns an array with all unicode values for emoji characters.

This is a function so the array can be defined with a mix of hex values
and range() calls to conveniently maintain the array with information
from the official Unicode tables (where values are given in hex as well).

With PHP > 5.6 this could be done in class variable, maybe even a
constant.

@return array
Returns an array with all unicode values for emoji characters .
