SeExprEditor updates

[Jonathan Topf]

Hi everyone, first off amazing work super handy and easy to build - that never happens with open source projects!

I Was wondering what plans exist for the SeExprEditor? I can think of a small improvements I would make to ux and I didn't want to change anything that people are working on or go against any design decisions that have already been made. 

The first thing I'd like to do is save/load scripts from the editor - should be a pretty easy.

The other thing is changing the ui to be based on Qt separators so regions can be resized manually by the user. 

I was also thinking of a slightly harder feature - adding a simple 3d view to preview 3d textures. Probably a bit hard for me but I'd like to look into it.

Thanks!
