academic/staden: Several fixes/enhancements

I notified upstream that Staden had been added to SlackBuilds.org
and got some handy tips. So:

1) The components of the program will now find their documentation
   directly.
2) The Staden package is now ready to provide a GUI for EMBOSS.
3) The real icons are used (converted from their Mac format).

 of DNA sequence assembly, editing, analysis and more.
 
 Some of its features include:
-GAP4 - Performs assembly, contig joining, assembly checking, repeat search,
-       experiment suggestion, read pair analysis and contig editing.
-GAP5 - The new development version of Gap4, designed to work with the large
-       volumes of data attainable through the newer sequencing technologies.
-PREGAP4 - Provides a graphical user interface to set up the processing 
-          required to prepare trace data for assembly or analysis. 
-SPIN - Compares pairs of sequences in many ways, often presenting its results
-       graphically and has a sliding sequence window linked to the plots.
-TREV - A rapid and flexible viewer and editor for ABI, ALF or SCF trace files.

 This requires io_lib and tklib.
 
 Notes:
 1) You should run the SlackBuild in real root environment (su -)!
-2) Make sure you have Emacs and Tetex installed, as they are needed
-   to generate the documentation.
-3) Slackware's TCL and TK sources are expected to be in /tmp at build
-   time. The SlackBuild will unpack them in the build directory and
-   create the necessary symlinks in /tmp. You can safely delete the
-   symlinks when the build is complete.
+2) Make sure you have Emacs and Tetex installed at build time.
+3) Although unsupported at the moment, SPIN can provide a GUI for the
+   EMBOSS suite programs. If you want to give it a try, run as root
+   "create_emboss_data" (EMBOSS should be installed, of course). This
+   generates some files in /usr/share/staden/tcl/spin_emboss/acdtcl,
+   so remember to manually clean them if you later uninstall staden.
