Added LOAD_MIO0_TEXTURE alias for backwards-compatibility (#349)

Sometimes tools like Fast64 will export script.c files with
LOAD_MIO0_TEXTURE() macro "calls" even when you have "YAY0" toggled
under the export menu.  To keep this from being a roadblock for
compilation, LOAD_MIO0_TEXTURE() is defined in this commit as an alias
to the LOAD_YAY0_TEXTURE() macro! :-)
