fix the list of old sage releases website

[was]

1. If I go to  http://sagemath.org/src/ there is only the last release.

2. If I click on "up one directory level", I'm just dumped to

 http://sagemath.org, which makes no sense.

3. Clicking on changelogs gives

 http://sagemath.org/src/changelogs/index.html which does indeed list changelogs. But it also lists a file "OLD_VERSIONS_HERE.txt", randomly right in the middle. Looking at that file I find the completely wrong statement: "These are archived old versions. For the new versions see the main SAGE website.  http://modular.ucsd.edu/sage".

4. There is a random "README.txt" for no reason also in the middle

of  http://sagemath.org/src/changelogs/

5. Finally, logging into the server I find that

 http://sagemath.org/src-old/ has the old versions. But how could I find that otherwise? Also, the description at the top of src-old doesn't explain what it is accurately. It would be better to say "Here you can download the source code for any past version of Sage so you can build it from source."

6. This listing at  http://sagemath.org/src-old/ also has various

random files like README.txt.in and install.html mixed in.

It would also be worth mentioning that we have many old sage install on sage.math.

I wonder if it would also be good to archive bdists for one specific Linux release, e.g., 32-bit x86 Ubuntu 8.04 LTS? Since then one can easily get a virtual machine and drop our binary in it.

Harald has fixed the problems involving finding the old source. Some of the directory listing and header problems remain.

Seems to me that almost every problem except the 6th problem is solved. There are still some random files at http://www.sagemath.org/src-old/

Harald, it seems to me that none of this is still relevant. Do you agree?

@jdemeyer: honestly, i have no memory of that. a short introduction note for the src-old files is the only thing that is still open. we can close it, i'll add a note.
