[Feature Request] Add an option to merge a filter profile into the current filter settings

[poWer4aiX]

As discussed in #207 having the filter profiles enables the users to quickly switch between different filter settings. This is very helpful specially when having larger sets of tags or versions.

We have use cases where we have more than 30 tags. They are organized into three or four groups / dimensions (e.g. for the environment like DEV, SIT, QA, PROD and test types like CKU, IT, REGRESSION, VERIFY). So it would be great to have the option to merge the filter selections from a profile into the current ones while applying it.

The resulting filter settings should be like a logical "sum up":

• For the filters where you have a selection the new selection should be added
• For the date / time related ones, the oldest fromdate, -time / youngest todate, -time (i.e. the largest horizon)
• For the amount the largest one
• For the run: If the new selection is violating the current one, then "All"

In order to be able to maintain a filter profile:

• there should be a dedicated Update Profile button, which opened the same dialog as when adding a new one, but based on the filter settings of the profile
• to overwrite a profile with the current filter selection, the Add Profile can be used while providing the name you want to overwrite.

Thanks,
