Subject: Fix the bug that prevents an introducer from starting when introducer.furl already... 
X-Git-Url: https://git.rkrishnan.org/pf/content/en/seg/biz?a=commitdiff_plain;h=2d16a16ee3d99482aba925ce54ab4d9dffe1bcf6;p=tahoe-lafs%2Ftahoe-lafs.git

Fix the bug that prevents an introducer from starting when introducer.furl already exists. Also remove some dead code that used to read old config files, and rename 'warn_about_old_config_files' to reflect that it's not a warning. refs #1385
