WaterlooWorks Plus

Adds quality of life improvements to WaterlooWorks.

What's new in 1.2.2:
- Changed extension name from "WaterlooWorksPlus" to "WaterlooWorks Plus"
- Fixed this extension for WaterlooWorks. Opening job postings in new tabs with middle-mouse button and ctrl+click should be working now, as well as opening inbox messages in new tabs.
- Removed the dropdown menu for opening job postings in current tab or new tab
- Fixed "Back to Top" link not appearing at bottom of page.

Current features:
- Open job postings in new tabs with [middle-mouse button], [Ctrl+click] or using the "right click context menu -> Open link in new tab".
- Improved table formatting for job postings and dashboard messages to prevent need of scrolling horizontally
- Adds clickable links to the subject text for the dashboard message table (supports new tabs)
- Shortened some table header names for better visibility
- Adds extra pagination to the bottom of job postings page
- "Back to top" anchor at the bottom of job posting pages
- Repositioned "Back Buttons" directly above and to the left of main content for ease of accessibility
- Stylish and persistent blue navigation panel to replace the ugly smoke colour
