filecount never updated

[dmd]

According to the documentation the metric mercure.master.router.main.incoming.files reports "Number of received DICOM files waiting in the incoming folder".

I believe this is supposed to be implemented here:

mercure/router.py

Line 111 in 686ea40

helper.g_log("incoming.files", r.filecount)

However, the variable filecount is initialized to 0 here:

mercure/router.py

Line 37 in 686ea40

filecount = 0

and then never updated anywhere else in all of mercure.
