Added QPhiX Solver... First pass
 *) Actually did a parscalar build of chroma with QPhiX

fixed any compilation related issues.
Checked that QPhiX integration works. Added some timing code in the quarkprop chain to track down missing time. Right now some time is still missing in linOp and invLinOp creations. Investigate this later
Cosmetic changes for QPHIX solver
Added test XML input
Merged qphix changes. Added NEWS file entry
