Merge branch 'election-css' into 'master'

Improved Elections CSS for the table

- Everything can be seen without scrolling sideways (unless you're on a small screen)
- Each column makes the same size
- Candidate description/program is now below its profile picture
- If the candidate does not have any profile picture, the default one is shown
- The Edit/Delete message has been replaced with their corresponding emojis (they takes fewer spaces and doesn't need to be translated)
- Modified links at the bottom to look like buttons
