Merge pull request #65 from japgolly/genopt

Added Gen.option. (Gen[T] -> Gen[Option[T]])
Add test for Gen.option
Simply drop support for Scala < 2.9.3 in Test.scala since you can't tell what other compatibility errors might pop up
Remove obsolete project files
nix build: Add some Scala versions
Update release notes in preparation for 1.11.0 release
Add explicit suchThat to Gen.conatainerOf combinators.

This also restricts Gen.containerOf to only handle
types that are implicitly convertible to Traversable.
This is required in order to be able to inspect
simplified containers.
Update README to refer to ScalaCheck site
Small README tweak
Prop uses Gen.Parameters directly instead of Prop.Params
Use scala.util.Random instead of java.util.Random in Gen
Change def to val in parameter types etc to guard for side-effects
Update release notes
ScalaCheck 1.11.0 release
Bump version to 1.11.1-SNAPSHOT
Add Gen.uuid for generating java.util.UUID instances
Fix some incorrect scaladocs
Better coverage for Arbitrary[Option[A]]
