Stein-Watkins database

[David Loeffler]

I was just looking at reviewing trac ticket #12092 (get doctest coverage of databases/stein_watkins.py to 100%). In the process, I noticed a bunch of silly things going on with the optional Stein-Watkins elliptic curve database spkg:

- The web page http://modular.math.washington.edu/papers/stein-watkins/ links to http://modular.math.washington.edu/ecdb/ecdb/, which doesn't exist (the second "ecdb" shouldn't be there).

- If you try to install the "mini" version of the database that is in the standard Sage optional packages list, by typing

sage -i database_stein_watkins_mini

then it doesn't work: you need to give it an explicit version number (sage -i database_stein_watkins_mini.p0). This doesn't happen for any of the other optional packages, which all seem to correctly find out what the latest version is and download that.

- There is a silly discrepancy in the file names: the mini database is "database_stein_watkins_mini" and the full one is "stein-watkins-ecdb".

We should probably fix these niggling little things before merging #12092.

The problem is the name of the package is missing a version number: it
should be something like
database_stein_watkins_mini-VERSION.p0.spkg

(where VERSION should be a date like 20120314 if there is no real
version number)

The same problem for the optional package

database_odlyzko_zeta.spkg
