add bool return for mouse-based E_Action callbacks

Browse Source 
in many cases, a mouse action's callback will fail to execute as a result of multiple
objects being under the pointer at the time of the event. in this case,
the callback should be able to determine whether action callback processing should
continue.

as an example, when attempting to execute an action which only activates for
client objects, if the passed object is not a client then the callback should return
false to indicate that it was not able to perform the action for the given object,
allowing further actions to be attempted on this object
