When repository contains a Slack type hook,
it changes original payload content.

This patch fixes it by using a local object to store
newly created Slack payload instead of assigning
back to the same variable.

- Update locales

path.Dir can't handle Windows case, must use filepath.Dir

- Change tooltip size from mini to tiny in profile page

- add tooltip for organization name in profile

- User profile un/follow
- List user's followers/following
