Remove reference to sbt.graph settings.
Upgrade to sbt 0.13.1.

Upgrade the following plugins:

  * sbt-scalariform
  * sbt-osgi
  * sbt-assembly
  * sbt-revolver

Remove xsbt-web-plugin because I couldn't find the right version. Remove
all references to xsbt-web-plugin from build file.

Add missing argument to StreamCopier constructor:

[error] /Users/grek/scala/spray/project/Utils.scala:46: not enough arguments for constructor StreamCopier: (bufferSize: Int)com.decodified.scalassh.StreamCopier
[error]     new StreamCopier().emptyToString(getClass.getClassLoader.getResourceAsStream(resource))
Remove sbt-revolver and sbt-assembly plugins.

They can't be resolved by my local Artifactory installation.
Do not use 'container' scope.

Since we removed xsbt-web plugin, we can't use container scope anymore.
Add dependency on scala-xml in examples.
Add dependency on scala-xml in benchmark subprojects.
Upgrade to shapeless 2.0.0-M1.

We build shapeless 2.0 in dbuild so I needed to update spray to that
version because shapeless 2.0 is not compatible with 1.x.

Main changes are around PrependAux -> Prepend.Aux,
HListerAux -> Generic.Aux and changes to package structure.
