ROLES AND PERMISSIONS - FIRST CHECK-IN

Browse source 
=======================================

WARNING:  DEV IS CURRENTLY VERY UNSTABLE.

This is a mega-checkin of the new Roles system.   A lot of changes have
been made in core and modules.

Currently there are a lot of rough edges and known problems.  We are
working hard on these .. .the reason for getting this into HEAD at this
stage is enable us to move faster (our branch was diverging from HEAD
too much).

Please keep an eye on http://docs.moodle.org/en/Roles for current status
and information for developers on how to use the new Roles system.

//
// Capability definitions for the chat module.
//
// The capabilities are loaded into the database table when the module is
// installed or updated. Whenever the capability definitions are updated,
// the module version number should be bumped up.
//
// The system has four possible values for a capability:
// CAP_ALLOW, CAP_PREVENT, CAP_PROHIBIT, and inherit (not set).
//
//
// CAPABILITY NAMING CONVENTION
//
// It is important that capability names are unique. The naming convention
// for capabilities that are specific to modules and blocks is as follows:
// [mod/block]/<component_name>:<capabilityname>
//
// component_name should be the same as the directory name of the mod or block.
//
// Core moodle capabilities are defined thus:
// moodle/<capabilityclass>:<capabilityname>
//
// Examples: mod/forum:viewpost
// block/recent_activity:view
// moodle/site:deleteuser
//
// The variable name for the capability definitions array follows the format
// $<componenttype>_<component_name>_capabilities
//
// For the core capabilities, the variable is $moodle_capabilities.
