performance proposal - Store data in static variable

[arashsaffari]

Each query for rights and groups sends a query to the database.

But you can save all rights and groups in a static variable at the first query and search only the variable at next query.

as an an example:
I use in a template file 6 times the function has_permission(). this function sends 2 queries to the database each time. total of 12 queries. . But you can reduce that to 1 or 2.

Thanks for your great job

Good idea. As of 136098f I'm part of the way there.

• User permissions are now cached using whatever cache engine is enabled at the PermissionModel level. Helps in several calls from FlatAuthorization.
• The User entity now stores user permissions (both user-specific and from their groups) in the entity to restrict that database call to once anyway.
