Harded-coded directory in MultiQC

In rule multiqc:

rna-seq-snakemake/rules/qc.smk

Lines 48 to 59 in 2cbc170

	output:
	directory("results/qc/multiqc/multiqc_data"),
	"results/qc/multiqc/multiqc_report.html"

	"../envs/qc.yml"
	shell:
	"""multiqc {input.reports} \
	--sample-names {input.sample_names} \
	--outdir results/qc/multiqc \
	-m fastqc

MultiQC expects a directory path to the --outdir argument, which means output and --outdir are both hard-coded in this implementation. There should be a way to move results/qc/multiqc to params.
