[ticket/11663] Make generate_text_for_storage return the errors.

generate_text_for_storage does not return anything, all returned values are outputted using the parameters so this uses the returned value with the same idea as many C language functions where the returned value is if all went well or not and if it didn't what went wrong.

[ticket/11663] Add the doc block about the return value.

[ticket/11973] Remove logic from tokens language array

Previously if a translator did no translate a token, it would not be
displayed. On the other hand, the translator could add additional tokens
which have no functionality.  Functionality is already hardcoded into
bbcode.php so we can that in the ACP aswell, in order to prevent namend
issues.
