Too many files open

[jakkn]

The command nwn-erf --create -0 -M -f module.mod gff_sources/* will throw 'too many open files' exception when building from sources that exceed user limit. Increasing the limit by running ulimit -n NUM where NUM is a number higher than the amount of gff resources is a suitable workaround for unix systems, but I have been unable to find a similar workaround for Windows.

Linux error:

I believe this is due to files being opened and never closed in bin/nwn-erf around line 177. I'm looking into this now as I'm having some issues with local dev. Although I'm also on a mac and had to modify the source to be able to pass directories in via the cli so things may be functioning differently depending on what OS you're using @jakkn.
