- Kernels are generated in build/ and no longer penetrate the source tree. Old kernel files removed. Users interested in ViennaCL-Nightly should consider creating a symlink viennacl/linalg/kernels pointing to build/viennacl/linalg/kernels and run 'make' in build/ after each pull.
- Issue with trans_prod_impl() in GCC 4.7 solved.
- Virtual destructor added in runtime_wrapper class within kernel generator
- Updated documentation for 1.3.1 release

* Added GPU-based Block-ILU preconditioner (extracted from ViennaSHE)

* Polished SVD: Now supports double precision, adjusted error bounds.

* Polished NMF implementation and tests

* Removed temporaries for C += prod(A,B) and C -= prod(A,B) including transposed variants

Initial sf.net commit of version 1.3.0 including a follow-up commit (removal of unnecessary indirection in inner_prod())
