Update trackers already in exodus

[pnu-s]

Hello there! I took a look to update the profile of (most of) the trackers which are already in exodus:

• Added the "in exodus? yes" information
• Added the signatures when missing
• Changed the header to use the template (## Tracker Name)
• Removed trailing white spaces

Hope this helps! :)
