#23 Allow Ident Searches to be Restricted by Filename

[AdrianIssott]

I.e. just like the general search is (inc. regular expression support). On large code bases you often know you want to restrict the search to a particular layer or component which can normally be achieved by restricting results to files containing, for example, "Bluetooth" or "Persistence" in their path.

Interesting idea, sounds worth implementing if the performance impact is not too great for the regexp matching.
