Allow choosing how filter rules are concatenated

Currently all filter rules are connected using AND.
So if several rules are defined for a filter, an entry must match all criteria to be displayed.
Though often you want to see entries, which match at least one rule.

In my example I wanted to display all tickets of a project and all its sub-projects.
So I would expect to be able to create a filter rule for the main project and several other rules for each sub-project. Of course a ticket can just be assigned to one project, so it should be enough, if one of the filters applies.

I just realized that there was already a request for this .

So for the case of selecting different projects it's working as expected.

Though:
1. It is not obvious at all that you can select several elements from the list.
So a little hint in the filter dialog would definitely help.

2. Many filter rules don't have a list to choose from (e.g. the project code).
Adding a selection list would help in these cases.

3. Sometimes you really want to connect two rules using OR.
Imagine I want to get all the projects, for which I am the manager plus all with project code "XYZ".
