A little refactoring

[Beniamiiin]

1. Replaced gen_command option module_targets to project_targets.
   Now you can write generamba gen Module template_name --project_targets Target1,Target2
2. Replaced rambaspec parameter file_name to custom_name.
   Now you can write in rambaspec something like this - {custom_name: "{{ prefix }}{{ custom_parameters.my_value }}{{ module_info.file_basename }}", name: View/ViewInput.h, path: Code/View/view_input.h.liquid}
3. Replaced rambaspec parameter file_type to is_resource.
   Now you can write in rambaspec something like this - {name: Resources/MyJson.json, path: Resources/MyJson.json.liquid, is_resource: true}. Then generamba adds this file in project like resource, and not like file reference.
