Title: Added a specialized version for norm(DenseVector[Double])

The changes put the performance of norm computation almost the same to a bare-bone implementation.

1. added @specialized(Unit) to foreach (~3x speed-up for norm computation).
2. added a specialized version for norm(DenseVector[Double]) (~6-7x speed-up for norm computation)

Added sbt-idea to plugins.
