textual_inversion.py: filename changed

[Woisek]

Now that I can successfully train TI with Automatic again, I've noticed, that the filename for the loss has changed.
It's now called train.csv, but it should be textual_inversion_loss.csv
I have scripts that rely on this name to work. It would be highly appreciate if this could be renamed back to the original file. 🙂
Thanks!

fixed - i've made it configurable in settings. default will stay as train.csv, but you can set it to anything.

Very cool! Thanks for this quick fix! 👍
