* Fixes issues with project paths w/ trailing slash
When launching AP with a --project-path that has a trailing slash, the
AssetBuilders would get that slash instead of a normalized version.
This would mess up the params sent to AssetBuilders.
* Missed a variable name replacement
* Addresses feedback on code style guidelines
Removed 'auto' keyword in favor of explicit types.
