* Add spacy.errors module * Update deprecation and user warnings * Replace errors and asserts with new error message system * Remove redundant asserts * Fix whitespace * Add messages for print/util.prints statements * Fix typo * Fix typos * Move CLI messages to spacy.cli._messages * Add decorator to display error code with message An implementation like this is nice because it only modifies the string when it's retrieved from the containing class – so we don't have to worry about manipulating tracebacks etc. * Remove unused link in spacy.about * Update errors for invalid pipeline components * Improve error for unknown factories * Add displaCy warnings * Update formatting consistency * Move error message to spacy.errors * Update errors and check if doc returned by component is None
