[Hw4mdl-devel] Patch for capabilities

[Ashley H. <as...@ne...>]

Hi all,

Here is a patch which demonstrates the use of roles/capabilities to 
define whether a user has presenter access or not to a Live Classroom.  
To edit the capabilities, as an Administrator to go Users -> Permissions 
-> Define Roles.  Edit a role, eg. "Student", and then you can change 
the capability called "Has presenter access to Live Classrooms".  The 
default settings are to have teachers and admins as presenters and 
students without presenter access.

I've added a liveclassroom_getRole() function into 
mod/liveclassroom/lib.php which is called instead of the generic 
getRoleForWimbaTools() function in WimbaLib.php.  The reason I moved it 
is so that Live Classroom and Voice Tools can have separate capabilities 
defined.

I have only tested this in 1.9 and the capabilities are only implemented 
for Live Classroom not Voice Tools, so this is just a proof of concept.  
If you are happy with this implementation I can do some further testing 
to get it working on older versions and also implement the capabilities 
for the voicetools module.

Regards
Ashley
