Support for letsencrypt.sh

[brrrrrrrt]

i really appreciate the work you have done and i would love to test it, hence to have letsencrypt within ISPConfig, but the hell of dependencies is keeping me from using it:

by now i am using a simple shell script which does the job in a perfect way without all the bloated stuff. Easy installation, simple configuration, automatic renewal via cron and even features the possibility for a hook script:

Hi!

Great work, I think minimum number of dependencies is essential for a better maintaining.

upgrading letsencrypt.sh is as easy as "git pull" :)

right now i am using letsencrypt.sh together with ISPConfig in the following way:

• add the domain(s) to the letsencrypt.sh/domains.txt file
• call "letsencryt.sh -c" to generate everything
• enter "using letsencrypt" in ISPConfig SSL-Key,-Cert,-Chain fields and "save" the certificate
• after ISPConfig has created the files in the SSL folder i replace them by symlinks to the letsencrypt files (the letsencrypt.sh generated paths are always predictable like certs/example.com/cert.pem)
• activate SSL on the domain - done. (certs get automatically renewed via cronjob)

"all" what would be needed from ispconfig would be a letsencrypt(.sh) checkbox and which adds/removes the domain to/from the domains.txt, call "letsencrypt.sh -c" and create proper symlinks instead of certificate files.

i use a global Alias for the challenge folder, which makes things easy, but the hooks of letsencrypt.sh could also be used to create temporary ones in the proper document root.
