Avoir contains Old French and Middle French lemma's

[jumelet]

The declension for avoir ("to have") is also present as "avoyr" (Middle French) and "aveir" (Old French), which leads to ambiguities for inflection. I recommend to remove the entries of these old forms.

Also, the lemma of être is encoded as the Old French "estre", which should be changed as well.

It's not just avoir where this issue is present, saw it for "savoir" as well ("savir" and "saveir").
