Download SRA by ID and convert it to FASTQ files

A simple way to get raw data (FASTQ files) from SRA should be provided. From the command line it can be done easily using the SRA toolkit utilities "prefetch" and "fastq-dump", see https://www.biostars.org/p/111040/, http://www.ncbi.nlm.nih.gov/books/NBK242621/.

In UGENE it can be done as a single action, i.e. a user inputs IDs and gets the files.
