[Include analysis] A few more UI improvements

- Show number of filter results. This also makes it more clear when
  a filter is active.

- Simplify the getState() function by using URLSearchParams instead
  of manual processing with regexes.

- Tighten the legend section and move it to the bottom.

- Put the go link in the header.
