[danielhompanera]

What

Adds a new button to the global revision control menu to open Lock Rules in Unity's Dashboard if the workspace points to a cloud organization

How

• It checks server's url and looks for @cloud to find out if it is a cloud organization.
• If positive if shows a new button saying "Configure Lock Rules" ("Navigate to lock rules configuration page in the Unity Dashboard.")
• If clicked on the button it launches a url pointing to Lock Rules configuration page for the cloud organization (using 'default' as generic id)
