Increase Username and Orgname MaxSize 35 -> 40

[segevfiner]

Change the MaxSize limit from 35 to 40 for the Username and Orgname fields. Our system uses GUID/UUID names and we needed a slightly larger limit for those fields. The DB schema already uses VARCHAR(255) from a default in xorm (http://gobook.io/read/github.com/go-xorm/manual-en-US/chapter-02/1.mapping.html).

Depends on go-gitea/go-sdk#149 (I haven't updated it in dep so that needs to be done once that PR is merged)
