Relax module naming restrictions

Forcing module names to be valid ninja names is an unnecessary
restraint on the project build logic.  Allow any string as a
module name, and sanitize and uniquify the module name for use
in module-scoped variables.

Also move the module scope to be per-module instead of per-group
so that modules can use the same local variable name for each variant.

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.
