Changed loading to work using probeset data

I want to use the blast hits to the probes to select
mitochondrial contigs rather than simply blasting
the whole contig to try and get a more accurate idea
of mitochondrial expression by using probes that
contain mitochondrial sequences.

None of the probes are perfect hits, at some point I
 will need to decide on a cut off point
Made mito_probes' header more accurate
Adjusted 2_clean.R for Array probeset data input

The rest should work fine now
