Removed comms initialization from initQudaDevice() for compatibility
with GPU Direct as implemented by mvapich (see issue #118)
Fixed memory with half-precision clover fields using texture objects (closes #117).
ColorSpinorParam is now a child of LatticeFieldParam.
Fixed instability in MR solver introduced when stopping condition was removed.
Merge branch 'master' of https://github.com/lattice/quda
Fixed typo in debugging print statement
To avoid underflow in solvers, both the source and initial solution vectors are rescaled such that the source vector has unit magnitude.  Closes #116.
Small fix to multi-shift solver test for wilson/clover fermions
Merge branch 'master' of github.com:lattice/quda into jitptx
