Fix for problem using the gerrit-trigger under Windows

The plugin works, though i personally feel we have too many quotes. Is that a problem in Linux too?


e.g. in the build properties i see

GERRIT_CHANGE_OWNER="""Robin Rosenberg""" <me@example.com>

I added an echo to my ant build file like this and it says
		GERRIT_CHANGE_OWNER=${GERRIT_CHANGE_OWNER}

GERRIT_CHANGE_OWNER=""Robin Rosenberg"" <me@example.com>
