Resolve HLint warnings

All warnings are either fixed or, if more appropriate, HLint is
configured to ignore them. HLint suggestions remain.

  * Ignore "Use camelCase" warnings in Lua and legacy code
  * Fix or ignore remaining HLint warnings
  * Remove redundant brackets
  * Remove redundant `return`s
  * Remove redundant as-pattern
  * Fuse mapM_/map
  * Use `.` to shorten code
  * Remove redundant `fmap`
  * Remove unused LANGUAGE pragmas
  * Hoist `not` in Text.Pandoc.App
  * Use fewer imports for `Text.DocTemplates`
  * Remove redundant `do`s
  * Remove redundant `$`s
  * Jira reader: remove unnecessary parentheses
