User interface changes

Changelog:

- Added a link to the post that is being removed in case people want to
copy paste things.
- Added the template of the header and footer to the pop-up so people
can see what is added.
- Moved elements to where they will end up in the removal post. The
footer is now below the reasons.
- Moved the log reason down since that is seperate from the removal
post, also because we reference to the "send" and "no reason" button
that are actually near there.
- Some general css changes in regard to text and element spacing.
