spaces in group name or user name list end up making %20 appear in virtualgroups.conf file

[jkeltz]

Issue Description

When adding users to a group in the virtualgroups plugin, if you insert spaces after the commas in the user list, then the users in virtualgroups.conf will have a %20 prepended to them. For example, add to group test1 user1, user2, user3. In virtualgroups, user1 will be okay, but user2 will be "%20user2" and user3 will be "%20user3". If you try adding the user without the space -- egg: user1,user2,user3 this will apply to the right user. Add a group, and insert spaces, and the same thing happens. Spaces should not be valid characters for user or group lists.

I ended up solving this issue with the following changes:

To fix the problems with spaces in users:

In addUserGroups after checkSecurityToken() line:
$user = str_replace(' ','',$user);

In addGroupusers after cleanGroup line:
$users = str_replace(' ','',$users);

In editUserGroups after checkSecurityToken() line:
$user = str_replace(' ','',$user);

In editGroupusers after cleanGroup line:
$users = str_replace(' ','',$users);

To fix the problem with spaces in group names:

In VirtualGroups.php in addUserGroups, after str_replace above, add:
$groups = str_replace(' ','',$groups);

In addGroupUsers after the previous user str_replace line, add:
$group = str_replace(' ','',$group);

In editUserGroups after the previous user str_replace add:
$groups = str_replace(' ','',$groups);

In editGroupUsers after the users str_replace add:
$group = str_replace(' ','',$group);
