Awestruct fails to start due to missing $LOG variable

[mojavelinux]

If there is an error loading one of the extensions, Awestruct fails to start when attempting to log a message.

Here's the backtrace to the error:

path/to/awestruct/lib/awestruct/extensions/pipeline.rb:6:in `rescue in block in <top (required)>':
undefined method `debug?' for nil:NilClass (NoMethodError)
    from /path/to/awestruct/lib/awestruct/extensions/pipeline.rb:3:in `block in <top (required)>'
    from /path/to/awestruct/lib/awestruct/extensions/pipeline.rb:2:in `each'
    from /path/to/awestruct/lib/awestruct/extensions/pipeline.rb:2:in `<top (required)>'

    from /path/to/awestruct/lib/awestruct/engine.rb:10:in `<top (required)>'

    from /path/to/awestruct/lib/awestruct/cli/generate.rb:1:in `<top (required)>'
    from /path/to/awestruct/lib/awestruct/cli/invoker.rb:4:in `require'
    from /path/to/awestruct/lib/awestruct/cli/invoker.rb:4:in `<top (required)>'
    from /path/to/awestruct/bin/awestruct:6:in `require'
    from /path/to/awestruct/bin/awestruct:6:in `<top (required)>'
    from /path/to/awestruct/bin/awestruct:23:in `load'
    from /path/to/awestruct/bin/awestruct:23:in `<main>'
    from /path/to/awestruct/bin/ruby_noexec_wrapper:14:in `eval'
    from /path/to/awestruct/bin/ruby_noexec_wrapper:14:in `<main>'

The problem seems to be that invoker.rb ends up loading the engine, which loads the pipeline, which attempts to use $LOG before it is initialized.

It also fails to create a new site (Init) due to invalid assignment in initialize method.
