Added "thumbnail view" to Experiment List page.
Added thumbnail rendering to renderer.

Note that thumbnail view is not available when viewing the idle list.

Also, loading thumbnails for "all" as admin takes a while!

Fixed error when specifying non-existant temp ns file id to spitnsdata.php3

(i.e. copy-and-pasting in an URL with the last digit of the ID truncated.)

Also changed one line of top2image.php3 to be <80 columns wide.

(we should remove the old ones soon)

These allow zooming and present (optionally)
  - Node type
  - Node IP listing
  - Link characteristics
     - always shows bw
     - shows latency if > 0
     - shows loss if > 0%

Added links in shownsfile.php3 for specifying zoom and more/less detail.

Got new visualization integrated...
Put .png files for icons in www/ (both src and build trees)
..those should probably be somewhere else eventually (at least in a subdir of www),
but they're happy there for now.

so that admins can vis any experiment (that is, have access to the
exp directory in the /proj/pid tree). Eventually we want a standalone
top file generator.

current testbed software practices. Add a wrapper script to go from
a pid/eid to the top file in the experiment directory. This means we
cannot visualize experiments that are not active, but until we have a
topfile generator that is independent of assign_wrapper, there is
nothing to do about that. A makefile to install new tools. Also add a
couple of web pages. The first web page spits out a page with an img
tag which refers to another php script that generates the gif file
with the backend tools, and stuff is out with an appropriate content
header line. Very nifty.
