STL export use object name

I do a lot of 3D printing,

It would be handy that the default STL export file name would be the object name when Selection Only is enabled, even when only a single object is selected

If this option is not selected take the name of the blend file. Optionally have a mark for prefix of the blend file for the object name.

I dont know who maintains it so posting it here, seams a general blender plugin.
