Better CPU for progress bars

• Refactored the Next Check In progress bars to use scaleX() instead of width to get the work on the GPU as opposed to CPU.
• Only hide the progress bar if there are more than 20 hosts/services down, up from previous limit of 10. We'll see how the GPU fix does and update this safety net further.
• Set the document.title from the title set in settings. This will cause the browser page name to match the title name you set. Supports Emoji also.
• Add some more text on the settings page which options affect client / server CPU.
• Added back in the version check which was somehow removed during the Recoil refactor.
