[Menu] Add MenuModule translation for dynamic menus

[craigh]

https://github.com/zikula/core/blob/1.4/src/docs/Core-2.0/Menu/Translation.md

probably will require Gedmo/Translatable

[rallek]

A simple way would be a kind of locale usage. Similar to e.g. the sitename. That would be consistent to the complete core.

For each language installed an own title filed. If a language will be added later the string of the first language will be used until it is translated real.

Closing as won't fix as dynamic menus are removed.
