Fixed static title of piRNAsignature tool output pdf (title always claimed 23-29nt). Introduced cheetah code to read the dbkey of the input dataset, and fetch the corresponding bowtie index from from the bowtie_indexes table. Moved input into RefGenomeSource conditional and added a validator tag, so that for the built-in index option it is verified that the bowtie file has a known dbkey.
