Showing sequence from BLAST database for BLAST results

1. For each BLAST result add a qualifier with the sequence from the BLAST database.
2. Add also another qualifier with the CIGAR value.
3. Show the sequence from the BLAST database in the annotation's tooltip. The mutations (differences from the original "quest" sequence) must be in bold. The tooltip should allow displaying of at least 100 characters of the sequence (in several rows).
