The `local` and `haddock` booleans are only used for determining the URLs to generate, so let’s make that clear.
The function does not really deduplicate the elements, it takes and groups. :)
Upstream does not think shadowing should be avoided, so let’s undo the changes to shadowing. Same with incomplete pattern warnings, we’ll just let it crash for now. Also drop the `Is*` prefix for the URL constructors.
CI unfortunately uses -Werror and tests against more modern versions of GHC, so any new errors will only appear on CI.
The way the template was filled was rather hard to follow. This tries to remedy it by splitting the code which infers the data from the list of targets, and the code which generates the HTML. The logic should be exactly the same, but we use a sort->groupBy to stable-sort Targets into their packages.

(This contains some of the refactor commits from #391, only the last commit changes showFroms substantially)
This pulls apart the display logic and the data munging in
showFroms, for ease of understanding.The resulting code is a bit longer, but uses a nice to understand pipeline of
sortOn,groupOnandmapMaybe.The main complications came from the fact that both the
packageNameand thetargetModuleare optional fields, but now it should be fairly straight forward.
