Add a test that generates progress graphs
Only start the progress graphs from 5 seconds in
Restyle the progress graph
Only show the filename in progress graphs, not the full path
Show all progress numbers in the JSON to 1 DP
For the textual summary show worst result at 4 different levels
Change $VERSION$ for HEAD in the version, so that when looking from the git repo it looks better
Commit fresh progress example data - 1 dp and 3 charts
Improve the progress report display
Move progress styling into the CSS
Better variable names in the progress messages
Note we don't use any functions from shake-util in progress
