Address CA warning
Incremented patch version,

in order to indicate that the addition of a Select overload for Queries
(methods returning values) is mostly a fix to address a ReSharper warning
(see https://github.com/ploeh/Albedo/issues/35 for more details).
Added CleanAll as a prerequisite for compilation.
