hugolib: Refactor/-work the permalink/target path logic

This is a pretty fundamental change in Hugo, but absolutely needed if we should have any hope of getting "multiple outputs" done. This commit's goal is to say: * Every file target path is created by `createTargetPath`, i.e. one function for all. * That function takes every page and site parameter into account, to avoid fragile string parsing to uglify etc. later on. * The path creation logic has full test coverage. * All permalinks, paginator URLs etc. are then built on top of that same logic. Fixes #1252 Fixes #2110 Closes #2374 Fixes #1885 Fixes #3102 Fixes #3179 Fixes #1641 Fixes #1989
