Added development flag in constructor so we can keep url's constrained.

- This would change class signature so should be tagged 2.0 and KMT can update witch 2 code changes.
- Prevents multiple:
(\Bootstrap::is(\Bootstrap::DEVELOPMENT)
			? 'http://dev.api.communibase.nl:8080/0.1/'
			: 'https://api.communibase.nl/0.1/')
		);
- Allows temporarily dev/production switching by just adding a boolean flag.
