This commit separates the email cleaning mechanism to a separated
function, and enables a proper cleaning of `mailto:` prefix, usually
found on invitations because users just copy and paste from external
source.
- makes the profile access more efficient (replace in-app joins to a
simple select query on profile table
- add partial support for access-tokens (still missing some RPC methods)
- move router definitions to specific modules and simplify the main http
module definitions to simple includes
- simplifiy authentication code related to access-tokens and sessions
- normalize db parameters with proper namespaced props
- more work on convert all modules initialization to use proper specs
with fully-qualified keyword config props
The rationale behind the refactor:
- Make available profile data to other middlewares without
the need to access to the database (mainly for error reporting).
- Align with codestyle with the rest of internal modules.
- Simplify code.
