Fixed missing emails in the author section.
As per #7936, here is the attempt in order to fix the missing emails as described.
Some things to note, most of the email format have the characters /dot/ and /at in them and that they had to be converted to the correct characters of . and @ respectively.
LADSPA plugins, however, are a different story. Originally, the solution was to manually change the email format but it did not work since it is dependent on the ladspa repository. Meaning, no changes can be made in , unless that repository is changed. Anyway, some author emails have a, rather, peculiar email format and that they've been manually changed. This case happens for the authors: Andy Wingo and Jesse Chappel. They both have spaces, and they are inconsistent with the other authors' emails present in the plugins/swh folder
