working double sequential mms solver on gpu
fixed incompatibility with cpu deriv_SB that was introduced by changes
in cpu code
fixed a bug:
compile w/o GPU_DOUBLE lead to segfault in gpu_deriv_SB, as two fields were not
allocated in this case
su3 matrix mult with +=
fixed a bug which lead to loss of dp
added basic double2 tex support via int4 detour
added a double Hopping Matrix aequivalent
bug fix in polynomial initial guess generation -> currently disabled
wrapped a  test_double_operator by a #ifdef MATRIX_DEBUG
working double inverter for nd doublet called sequentially from gpu mms solver
removed the forced minimum iteration number in ND mixed solver
some restructuring to make transition to double2 easier
local dev_spinor_d[6] -> double4[6] such that we only have to adapt
loads and stores from/to global mem
working ndrat ndratcor monomials
added working TRUE mms solver in pure double
added possibility to specify a maximum number of shifts to be used in
this solver
adapted debug_level for printing out pre/post gauge-fixing data
fewer output by addign #ifdef LOWOUTPUT
changed some comments
removed some further output
fixed a small bug when benchmark is on
fixes a bug that lead mms solver to break too early
fixed a wrong pointer type
added relativistic basis in double nd operator
