Gender-Star-Remover eftir SpiritCroc

Constructions such as "gender stars" recently emerging in German language can make texts quite hard to read.
Accordingly, this add-on replaces these constructions on websites with an easier readable substitution, which can be chosen by the user.

Examples:
Expert*In -> Expertwesen
EntwicklerInnen -> Entwicklerwesen
Lehrer(in) -> Lehrerwesen

It is possible to freely choose substitution texts for both detected singular and plural forms separately.
However, the grammatical context is not taken into account, since this in general requires knowledge about the semantics, which are hard to detect programmatically.
