update SageTeX spkg to 2.2.3.p0 to fix spkg-check script

[dandrake]

The SageTeX spkg shipped in 4.3.2 has a slightly broken spkg-check: if LaTeX is present, but the tkz-berge.sty file isn't, the example file included with SageTeX cannot be typeset and spkg-check fails. Since I don't assume the user has LaTeX installed, I shouldn't assume that tkz-berge.sty is either.

There are also some documentation fixes, including notably an "egrep" which should be "egrep -v"!

Finally, the license for the documentation is now CC BY-SA; I've dropped the noncommercial clause.

The new spkg is version 2.2.3.p0 in http://sage.math.washington.edu/home/drake/code/sage/st/ . The last version of the spkg is available in the same place, for ease of reviewing.

Work Issues: portability issues in spkg-check

Could you modify the file spkg-check to conform to the portability issues at #8255? For example, the following line in spkg-check is not recommended:

if [ "$(which latex)" -a "$(kpsewhich tkz-berge.sty)" ]

I'm guessing you didn't mean to refer to this ticket... :)

Let's pretend I was referring to #7632 :-)

Thanks for the link. Ironically, I put in "-a" in an effort to be more portable...thanks for setting me straight. I've replaced the spkg with an updated one. Please review.
