Merged requested to merge 13-fix-verbose-bool into master
This MR provides a workaround for the "boolean" parameters that can't be passed as real booleans in Centreon.
We also log in broker log if parameters are set with now incorrect types: this will help users identify old configs where they used strings "true" or "false".
Plus a global README update/review.
This MR should remain "draft" until the matching changes in French docs are ready (for doc.canopsis.net).
Closes #13 (closed)
