plone.recipe.zeoserver has no way to specify TMPDIR

As of plone.recipe.zeoserver-1.1.1, I could not find a way to specify the TMPDIR in buildout.cfg, but didn't want to do it by hand. The problem occurred to me after experiencing this problem: http://<email address hidden>/msg32648.html

Therefore I created a patch that allows the user so say

tempdir = /path/to/huge/space

in the [zeoserver] section of his buildout, and have this then transformed into a suitable (?) setting in the zeoserver script.
