This commit removes the command line option for svn2git since it ultimately passed its value to `svn-git.
If the SVN transport requires a password, svn-git will always prompt the user for it, so now svn2git will detect the presence of the SVN2GIT_PASSWORD environment variable and pass its value in reply to the prompt.
git-svn does not support --password anymore.
