Fixing 404 on page view when using PostgreSQL

closes #1801
- adding fixBools method to `server/models/base.js` to convert bools to 1/0 to be consistent with MySQL & sqlite3 data providers (based on @ErisDS recommendation)
- this in turn fixes the check in `server/controllers/frontend.js`, which does an explicit `post.page === 0` comparison (in pgsql this is a `boolean`, since the schema declares it as "bool" in `server/data/schema.js`, but MySQL/sqlite3 don't have concept of Boolean, only an integer or bit)
- any model retrieved from persistence will pass through this (possible future refactoring is to combine fixBools & fixDates into one "canonicalize()" to have a single loop pass)

New URL helper - URL consistency fixes

fixes #1765
fixes #1811
issue #1833

New UrlFor functions

- moved body of url helper to config.path.urlFor, which can generate a URL for various scenarios
- urlFor can take a string (name) or object (relativeUrl: '/') as the first
  argument - this is the first step towards issue #1833
- also added config.path.urlForPost which is async and handles getting
  permalink setting
- frontend controller, ghost_head helper, cache invalidation all now use
  urlFor or urlForPost all urls should be correct and consistent

URL Consistency Improvements

- refactored invalidateCache into cacheInvalidationHeader which returns a
  promise so that url can be generated properly by urlForPost
- moved isPost from models to schema, and refactored schema to have a tables object
- deleted posts now return the whole object, not just id and slug,
  ensuring cache invalidation header can be set on delete
- frontend controller rss and archive page redirects work properly with subdirectory
- removes {{url}} helper from admin and client, and replaced with adminUrl
  helper which also uses urlFor
- in res.locals ghostRoot becomes relativeUrl, and path is removed

- xss santization does some odd things. This isn't needed until we have multi-user support, and we are investigating better solutions.

ghost-busboy improvements

- use hex instead of base64 as this can cause errors when trying to reopen the file due to characters like '/' appearing
- added basic console log to errors.
Use ajax for import

- changed POST /ghost/api/v0.1/db to be used with AJAX
- cache invalidation header should now work for import
- moved busboy middleware invocation to routes/api and routes/admin
