Solution: Replace Silverlight with Portable library
Instead of a specific Silverlight version, we now provide a separate
Portable Library assebly that supports .Net 4.0.1 and higher,
Silverlight 5 ad well as .Net for Metro style apps (WinRT).
New NuGet Package MathNet.Numerics.Portable with the portable library.
Since MathNet.Numerics.Portable now supports silverlight, the normal
package MathNet.Numerics no longer supports it (.Net 4 only).
Reworked the common parallel execution infrastructure for more reasonable
abstractions and better compatibility with portable libraries. Portable
libraries do support parts of the TPL, but neither the Parallel class nor
straight threading.

Sparse Vectors: Equals now supports accidential zeros. Fixes gh-21.
Equals previously returned always false in case of (asymmetric) accidential
zeros. Instead, Equals now expects accidential zeros and treats them
correctly (so we can allow arithmetic algorithms to generate accidential
zeros, avoiding a lot of zero checks).

Sparse Linear Algebra: complex vectors now override right Equals. gh-20.
Previously sparse vectors for Complex and Complex32 did override
Object.Equals instead of the generic IEquatable<Vector<T>>.Equals.
Now only overrides the generic version to ensure that the right version
is called in all code paths.
