simplecert.Init should maybe init with previous certificate when renew fails on init

[azukaar]

This is an extension to #14 that was fixed earlier:
Here's a scenario:

• I have a working certificate with 3 domains including the main domain for the administration
• I add an additional domain from the administration, and restart the server
• SimpleCert will try to replace the certificate with the 4th domain
• The 4th domain is invalid, so It will fail to init, the admin panel won't be accessible anymore to fix the 4th domain

How I could see this could works, is for example having a setting "fallbackToPreviousCert" that would do exactly what it suggest when failing to review on init? What do you think?
