#19 Change Novoalign Genomic Alignment workflow output filename

[Tony DeBat]

The Novoalign Genomic Alignment workflow takes two input files for a paired end read. The filenames might have names like "s_6_1..." and "s_6_2..." representing reads one and two from lane six. The workflow is expected to output a single file (it's doing this correctly) with 'pe' in the name. Something like "s_6_pe...". Currently the output file is incorrectly called "s_6_1...bam".
