New methods snakeCase and camelCase in \Rbs\Stdlib\String
Fix rendering of warning messages in console.
Some updates in dev commands:
 - add rbs_dev:initialize-block command to add classes for a block
 - add rbs_dev:devrest command to (de)activate devrest.php
 - rename rbs_dev:create-command to rbs_dev:initialize-command (homogenization with other commands)
 - some fixes in rbs_dev:initialize-command (mainly to deal with the new path of project's modules)
 - some refactoring to match with the default organization of commands (move command listeners and assets from Events directory to the Command one)
Code formatting.
Fixes and refactorings on addresses:
- Add getLines method on AddressInterface. It should be used to get the formatted address (getFormattedAddress in GeoManager should be used only to prepare an address before saving it).
- Add getFieldsLayout method on AddressFields document, returning the result of getFieldsLayoutData if it is not null or an auto-generated layout instead.
- In Address document, automatically fill the __lines value (returned by getLines).
- Some fixes in ManageAddress block, front office address form and order process address refresh.
Add missing correction="true" attribute on tax list in BO.
