debian: New version 0.95.3

This patch includes the changes to create the package for
debian.

Changes are included in changelog:

  * New upstream release 0.95.3
    * Removed debian/clean file. Upstream removes now the files.
  * Bumped to standard version 3.9.3
  * Important!: Removed symbol "W_DraggingInfo" in libwutil2 and
    libwings2, because the struct W_DraggingInfo is now declared
    as "typedef", therefore the struct is not included.
    This change is included in upstream, see line 126 of the file
    WINGs/WINGs/WINGsP.h
  * Patch 53_Debian_WMState.diff changed, because the WMState file
    in upstream is now different. Now, the dock launch WPrefs.
  * Removed /etc/X11/WindowMaker files.
