DOC/DOT import change broke Open File dialog

[rob . campbell]

I can't say for sure that this is a result of the recent 
changes that allow "dot" files to be opened as if they 
were "doc" files.  But it seems likely, since it happens 
on the latest nightly build but not 0.7.13.  I am using 
the win32 version.

When you specify the "Microsoft Word(.doc,.dot)" file 
type in the Open dialog, AbiWord won't show files of 
either type.
