A dialog for File->Merge

[micheus]

I've numbered some items in the post #56. Here the answers:
(1) Fixed.
(2) I made it this way: if no selection came from the file being merged after you checking "Make all new ... Selected" the radio button is automatically switched to "Add to the current".
(3) I'm probably going to use "Replace elements" after assigning this option for each project element.
(4) I think I found the problem and fixed it.

By filtering out textures I meant that I am thinking that textures (images used as diffuse, bump, etc. for materials) should not be listed in the list of materials. Maybe I am wrong???

doesn't it sounds strange? Images are not listed (yet), but if come to be I think to put into a separated groupbox.
But, if we are talking about the images used by materials not be shown in this new groupbox, then I think that it makes sense and it should be imported only if the material be imported too.
