Fix: Inlined CommandThread class to get rid of lib not found error
Fix: Removed buggy implementations of is_enabled() function. A better one is needed that applies to nodejs instead of git.
Fix: Copy pasted the functions: _output_to_view and scratch in a updated version compatible with sublime 3. They are copyed from the Git package.
