"Search pattern" group on the "Search in Sequence" tab

In UGENE 34 patterns on the "Search in Sequence" options panel tab in the SV can be either input by a user or loaded from a file. However, this is not clear enough the these two options are mutually exclusive.

Modify the "Search in Sequence" tab layout as shown on the attached image "modify-search-in-UGENE-35.png", i.e.:

1. Add a group that includes two mutually exclusive combo boxes: "Input patterns" and "Load patterns from file".
2. The group name should be "Search pattern", the "Search for:" label should be removed.
3. Remove the "Path:" label.
4. Change the widgets layout as on the image.
5. When "Input patterns" is selected (the default option), the pattern field is enabled, the file path field and the browse button are disabled.
6. When "Load patterns from file" is selected, the pattern field is disabled, the file path field and the browse button are enabled.
7. All search scenarios should work similarly to the UGENE 34 version.
