Finding the best auto completion sorting

[WebFreak001]

Hi all, there have been sorting improvements made in serve-d 
which will affect how user's auto completion will look like when 
having broad matches. [(1)]

To get a better starting point how you prefer it I would like to 
do a survey where everyone sends in their preferred sorting rules.

For this please visit https://completion.webfreak.org/ and submit 
your preferred sorting for this broad auto complete case.

In reality not all types can even be shown at once, (e.g. both 
`opBinary` and `init` at the same time would be impossible) but 
for the general case this is helpful in finding what users expect.
