Rename the repository to inbuxa-webmail

The repository moved from inbuxa/ihasmail-inbuxa to inbuxa/inbuxa-webmail,
matching inbuxa-server and inbuxa-admin. Point the source links, the image
name and the package link at the new name. The OAuth client id stays
ihasmail-inbuxa, since that is what the server registers.
