closes#1757 and #1773
- switches routes.frontend for posts and pages
to use a regex with two capturing groups. This removes
the need to dynamically remove an express route at a
later point, leaving the decision making to frontend
controller.
- added unit tests for all routing conditions that
can arise for posts and pages.
- updated functional tests to also test for same thing
in unit tests
- removes old code from server/api/index that used
to fix this issue, but is no longer needed
- removed some un-needed require statements in routes/admin
covers 90% of #755
- moved ghost.settings to api.settings
- moved ghost.notifications to api.notifications
- split up api/index.js to notifications.js, posts.js, settings.js,
tags.js and users.js
- added instance.globals as temp workaround for blogglobals (Known
issue: blog title and blog description are updated after restart only)
- added webroot to config() to remove `var root = ...`
- changed `e` and `url` helper to async
- updated tests
