Layer/Brush as Guideline

[NathanOtano]

Yop!
To avoid dependency problems, I usually import an image as a brush, put it in the library and then use it as an image guideline wwhich is quiet cumbersome. I would like to :
- Be able to directly send my layer or brush or display to an image guideline
- Have a way to go to "guidelines" "add" "image" and import it while incorporating it in the project instead of having it as a dependancy

Also, when a dependancy isn't found I have the warning each time I go back to the projects tab and not just when I open it which bother me a bit ^^
