Rename "originalFileName" in "filename" + definition

**Term**: `originalFileName `
**Current definition**: "Original name associated with a file (without path) in the context of the analysis software package."

Is this too precise given the term name?
	
@khelm `20:19 9 avr.`
I agree. No need to bring in the analysis software part

Another one ripe for reuse/mapping per (http://purl.obolibrary.org/obo/OBIws_0000001):
"A textual entity that refers to a digital document derived from a computer system."

+1 to Karl, too--it's a fileName. Do we need to specify with or without path?

As far as I understood, the full path would be stored in a prov:location attribute while the 'fileName' attribute would be used to store the original name associated with a file (con_0001.img, beta_0002.nii, pe1.nii.gz...). If I am correct this was suggested by +satrajit.ghosh@gmail.com in order to keep track of the file names that can be lost once the file is copied (e.g. imported in Neurovaut).

I like the "digital document name" definition suggested by Nolan, could we re-use it?

+1 for the OBO version
