Find should search the action text for steps

[pjaquiery]

To allow all the steps of a particular type to be found, Find should search the action attribute text as well as the currently searched text.
For example, to find all the places email is sent from a script a search for "Send Mail" could be made.
At present that can be done by searching for text that is likely to be unique to "Send Mail" steps (such as the Mail Server parameter), but that is not very direct.
