[REF] point_of_sale,web(site): move session info into page source

This commit introduces a mechanism to add information into the session
from a different module, without having to fetch it manually with a rpc.
This is intended to be used with small pieces of info required at the
start of the web client, such as currency informations.

To add information to the session, one can simply inherit from ir.http
and modify the session_info method.
