Be tolerant of extensions that are in capitals

[julien-lecomte]

This MR makes the tools accept files ending in capitals (eg: .GIT) and not only in lowercase.

This is needed only because the files in my toolsets temp0 folder are in capitals.

Testing

Before:

$ nwn_gff -i /tmp/plc_bookpiles.UTP -o /tmp/plc_bookpiles.UTP.json
Cannot detect file format from filename: /tmp/plc_bookpiles.UTP

After:

ls /tmp/plc_bookpiles.UTP.json
# ls: cannot access '/tmp/plc_bookpiles.UTP.json': No such file or directory

nwn_gff -p -i /tmp/plc_bookpiles.UTP -o /tmp/plc_bookpiles.UTP.json

ls /tmp/plc_bookpiles.UTP.json
# /tmp/plc_bookpiles.UTP.json

Changelog

Changed

- lib: Now accepts file extensions in capital letters.

Wish that was fixed in the toolset, and new files be created in lower case.
