#212 Files fail to load after adding module comments.

[Frithiof Andreas Jensen]

If the lines similar to: '#Boa:Frame:wxFrame1' are moved
or modified in any way - except for appending ws - the
loading of the files in a project will fail with 'TypeError:
unpack non-sequence'. Nothing happens until project is
opened again, which is most disconcerting to the poor
user who thinks some major corruption just happended.

'Add Module Information' does just that, by inserting the
module information before the 'file identification string'.

I think simplest fix is to insert the module information
*after* the file metadata, and perhaps document the
significance of the '#Boa:Frame:wxFrame1' comment
lines.
