Use a macro for all foo_RES to MR_foo conversions

Browse Source 
This makes it easier to understand what is happening in each of those
places, and also much easier to find the places that conversion between
hero and monster resistances happens (since you can now just grep for
"res_to_mr").  I think I got all the instances where the macro should be
used but I'm not 100% sure since there wasn't a single unique term to
search for to find them all.

I replaced the modifications to give_u_to_m_resistances made in the
previous commit, so that it now uses the same macro as other
conversions, since otherwise it would be much harder to find the
complete list of places where conversions between hero and monster
properties happen.
