More Polishing (#428)

# Added
- Added: Added a new button on admin dashboard to clear cache for the whole server

# Changed
- Changed: Moved the download logs to the new System page
- Changed: Tag Badges now show the correct cursor to help indication actions. For example, Collection badges on series detail page can be clicked, while type cannot.

# Fixed

- Fixed: After Scanning a series, clear out any cached chapters
