Multiple Sequence Reading Mode Dialog: Add feature to join sequence file with annotation file by name

Often biologists have separate files with annotations and sequences. For instance seq.fa and ann.gff

There must be a way to automatically join sequences and its annotations when they are opened by UGENE. One of the ways is joining by name. If multiple files are selected to be opened there must be a new option in the Multiple Sequence Reading Mode Dialog - "Join files with similar name in one document". That's how files like seq1.fa, seq1.gff, seq2.fa, seq2.golf will be opened in a convenient way.

Also the dialog must be renamed. It must be Multiple Files Reading Mode Dialog
