Adding new script to generate Intellij projects.

- Creates modules and includes only dependencies that are needed by
the parent module instead of including the entire source tree. The
new structure makes intellij much more responsive and fast.
- Adds proper android facets when AndroidManifest.xml exists for
quick resource lookup.
- Automatically includes intermediates directory for generated R files.
- Exclusion of un-neccessary language resource folders from id lookups.
- Automatic vcs configuration for git roots.
- Multi-module make file support.
- Aggregate modules for multi-module make files.
