work around rendering bug by changing source order

Having the inline style element that sets up the hower styles for list
elements at the start of the template triggers what must be a rendering
bug in Chromium causing the popup to be absolutely positioned with its'
top left corner at the center of the browser window instead of being
fully centered. Moving the same inline style to the end of the template
avoids triggering this issue.
Moving popup template to own file

HTML code of templates is now maintained in external HTML files.
This allows for easier editing and the HTML templates are compressed before being inserted into the userscript, thus, saving bytes.
