Modifications to rayshade

[Jose' C. <cru...@ce...>]

in RT.cpp  we've added a procedure (called rt_tweak)where touch the =20
parameters, shortly there we will control part of these parameters =20
via renderer properties.

Also, we've added support for spherical lights, to test them, change =20
the last parameter in line 383 of file RSRegister to a value like the =20=

radius of your light (test an scaled value of about 10cm)
