UIEditor : Sanitize new preset names

[mattigruener]

Hey John,

quick one to address SG14300. Ticket text:

"if i add a preset value to a plug with a name like
something / something
it seems to interpret the / as a submenu and i can no longer edit items in the preset list"

Would you rather have this replace the / with a space or something else?

Matti.

Thanks Matti - _ makes sense to me. I've merged as I think this is a good short term fix, but I'm going to leave a few comments here for future reference :

• I think the "'/' makes a submenu" thing is actually reasonably useful, and I do use it when making presets via scripting. We probably also need a way of disabling that - maybe escaping?
• The "/" throws the preset listing off because the preset listing is a PathListingWidget, and paths treat "/" differently.
• In the past I tried keeping support for "/" by doing some remapping back and forth in the Paths given to the PathListingWidget, but it quickly got a bit more involved than the quick fix I was looking for. I think this might still be a worthwhile longer term approach though.
