Fix bug when copying slice to itself

If proptools.CopyProperties is passed two values that point same
slice then setting the destination slice to a new slice will
overwrite the source slice, and the properties struct that is both
the source and destination will have an empty slice.  Copy into
the new slice using a new reflect.Value, and then update the
destination.

Blueprint Build System

Blueprint is a meta-build system that reads in Blueprints files that describe modules that need to be built, and produces a Ninja (http://martine.github.io/ninja/) manifest describing the commands that need to be run and their dependencies. Where most build systems use built-in rules or a domain-specific langauge to describe the logic for converting module descriptions to build rules, Blueprint delegates this to per-project build logic written in Go. For large, heterogenous projects this allows the inherent complexity of the build logic to be maintained in a high-level language, while still allowing simple changes to individual modules by modifying easy to understand Blueprints files.
