[IMP] translate: add add/radd methods on _lt class

In order to ease the usage of lazy translation, add the possibility to
add the _lt objects together and with strings.

Adding two _lt objects together or to a string will execute their
translation, so these operations still must be done once the user's
language has been defined.

For example, this is now possible:

    MESSAGES = {
        1: _lt("Hello, world!"),
        2: _lt("Lorem ipsum"),
    }

    def get_text(code):
        return _("Text is: ") + MESSAGES[code]
