windows.c: added device retrieval from subsurface_fill_device_list()

subsurface_fill_device_list() now goes trough the list of registry
entries in the SERIALCOMM key and adds all present values (such as
COM1, COM2) to a GtkListStore. Once done the function compares
all logic drive label to a static list of known DC labels,
such a 'UEMISSDA', which is the only present one at the moment
and adds any matching drive letters (e.g. C:\, H:\) to the list store
as well.

If no serial ports were added or no matching logical drives were found
the function simply adds a default entry named "COM1".
