general comment on the directive names: they should consistently follow the naming of the module so they should all start with "slBuildDeploy[DirectiveName]".

It seem like a pain in the ass but it really helps to be able to find the offending directive source code when debugging from an HTML template due to the angular directive name normalization.

eg it is easier to find this code: 
```
<sl-build-deploy-directive-name></sl-build-deploy-directive-name>
``` 
than this:
```
<directive-name></directive-name>
```
