Call route stack on handle
Update presenter reference for restful show view override
Make grouped routes available in lookup without referencing group; namespaced routes must be looked up by group
Brought sanity to route building (internal only; no public api changes)

- created a common context for route block evaluation; used for both
  main route blocks and nesting (groups/namespaces/templates)
- removed old RouteTemplate
- refactored tests
Handle edge cases around member routes in template expansion

- member routes are always moved to the end of the eval (so they are
matched last; routes in the template have priority)
- update member route paths when changing nested_path from within a
template
Fix missed merge conflict
Reopen log on prepare
Merge branch 'master' into 0.9-dev
