Auto-generated lemmas appear before declaration

[alreadydone]

For example, FundamentalGroupoid.ext_iff appears before FundamentalGroupoid, completelyRegularSpace_iff appears before CompletelyRegularSpace, Pi.nonUnitalRingHom_apply appears before Pi.nonUnitalRingHom. These are due to the attributes @[ext], @[mk_iff], and @[simps] respectively. The additive version produced by @[to_additive] also comes before the multiplicative version (e.g. EckmannHilton.AddZeroClass.IsUnital) but those don't necessitates a fix.

(Inspired by #161 which is also about ordering)

doc-gen sorts declarations according to their declared line number:

doc-gen4/DocGen4/Process/Analyze.lean

Line 145 in 96147ea

res := res.insert moduleName {module with members := module.members.qsort ModuleMember.order}

if the declared line number of the generated things was below the original things it would sort correctly.
