Comment for translators
Refactored library handler into dedicated methods for handling various types of requests
Switched to require_http_methods instead of explicit checks
Extracted total key length check into a method on ViewUtils
Added lettuce flavored scenario descriptions to library bokchoy tests
Removed Tools block stub
Improved user-facing and logging messages in library creation routine
Moved click_add_button to utils as it might be useful not only for Library Blocks
