Title: FAME Makefile adds -fdefault-real-8 or -r8 to make double precision.

Without this I get the following warnings from gfortran:

'''
_modes.f90:58.47:
qt = ((2 * 3.141592654 * mass) / (6.626e-34 * 6.626e-34))**(dim/2.0) * V
1
Warning: Arithmetic underflow at (1)

Do you think this has been much of a problem?
(or rather, how much of an improvement double precision will make)

@jwallen - please check that you think this is a good idea before merging.
Perhaps we should do something similar to the other fortran codes?
Oh, and if you're able to test on g95 that'd be great.
