hoverhandler: add priority system to determine which tooltip is shown

Browse Source 
Hover handlers now have a priority which is used to determine which
handler's tooltip is shown. The handler with the highest priority is
used, or, in the case of equal rankings, the first registered handler.

The base handler implements a default basic priority system based on the
diagnostic and help properties. Derived handlers can manually set the
ranking value as part of the identifyMatch() call.

A new checkToolTip() method is added so the handler can analyze whether a
tooltip is valid without it being shown.
