Rudder

In the directive tree, one line can contain up to 3 tool tips in a very small area, this is hard to maintain and not needed:

A directive tool-tip should instead be unique, short, and contain:

• the number of rules using this directive
• eventual warnings
• tags

Currently, we have:

• tags
• name of the directive (redundant as we put our mouse over the title to show the tooltip....)
• the technique version, which is also displayed outside, and is redundant
• eventual warnings
• agents compatibility which is displayed in the tree and is redundant
• policy mode which is displayed in the tree and so, is redundant
