Provide the combination of AND and OR in filter creation

[dpbraune]

Currently, you can create an AND filter (this AND that AND Sam) that triggers on the match of all of the AND parameters. Similarly, you can create an OR filter (this OR that OR Sam) that triggers on the match of any of the OR parameters.  However, you can only create an AND/OR filter (this AND that) OR (Sam OR Jim) manually (by editing the filter script) that will only trigger on a match to this and that combined with either Sam or Jim. Note: this could be done with two unique filters but I have too many already.

Filter creation should provide the capability to create more complex AND/OR filters without the need for manual editing of scripts.
