Users, Groups and Permissions links rendered as text

The tables displaying users, groups and security domains contain links, but they have no different colors nor font style than the other strings on the same tables.

STEPS:
------

• as 'admin' on the 'quickstart'
• click the cog icon 'Admin' to go to the Control Panel
• click Users
• compare the rendering of the word 'admin' (Username column) and that of the word 'repository' (Type column). Nothing * really says that the former is a link, while the latter is plain text.
• click Control Panel in the breadcrumb, then Groups
• compare the rendering of the word 'admin' (Group name column) and that of the line 'admin,workflowuser' (Members column). Here as well, nothing * really says that the former is a link, while the latter is plain text.
• click Control Panel in the breadcrumb, then Permissions
• compare the rendering of the word 'defaultread' (SecurityDomain column) and that of the line 'groups: everybody' (Role: readonly column). Here again, nothing * really says that the former is a link, while the latter is plain text.

• unless the mouse is hovering over the piece of text in which case the cursor turns from an arrow to a hand.
