As an editor of Wikidata-Lexeme I want to be able to add a new Sense and save it in a Lexeme in order to describe the different meanings of a word.
* I can add a new Sense to a Lexeme
* The Sense gets a stable, non-reusable ID
* The Sense always has at least one Gloss
* The Sense is persistently stored/survives a page reload
**Given**: I am on a Lexeme page
**When**: I click "add Sense"
**Then**: I get an input field for a new gloss and a language code and provide those
**Then**: I click save
**Then**: the new Sense is added with a new ID in the pattern L123-S1
**Personas to take into account**:
**Niels** - Active editor on Wikidata
**Alex** - Data user in small startup
