[Bf-committers] Import based on extension

[Jan Albartus]

I am unsure how practical this workflow would be;

Import an object using the 'default' import settings. Then have in the 
toolshelf (on the left) the import options which a user can tweak. 
(changing an option will cause the current imported to be removed and 
re-import with the new settings.) This would mimic the way a new mesh, 
say a circle, where the user can change the radius/vertices as long as 
nothing has been edited.

The problem becomes then that re-importing the mesh could take longer. 
(maybe an apply button?) The advantage could be that instead of making 
the selection up-front, it can be done after 'import'.

I am unsure how practical (from a user's perspective) that would be 
though. Maybe setting the import options on forehand is the best way to 
go. It would be the first application to change import-settings after 
import?
