Ignoring %appdata% or %userprofile% changes prior to launch

[gordonfpanam]

In an attempt to work around #146 I tried changing the environment variables %appdata% and %userprofile% in a separate CMD session before running letsencrypt.exe. It's just a simple:

set appdata=%allusersprofile%

...which would change this for that session only to point somewhere else. If I do this for %appdata% neither the displayed config folder or cert folder change. If I instead change where %userprofile% points then the leading components are omitted and the folders reference the current folder instead.

I could live with it referencing the current folder I suppose, but that's not how I figured this was using the environment variables. Normally one doesn't go mucking about with system-defined environment variables, but after checking that these are set per process (or per CMD session) only, I figured it wouldn't hurt to try on my test server.

I do see a fork that supports changing the config folder in .config but that hasn't been merged here.

This will be fixed in v2 with the --configpath parameter. See PR: #394
