Initial version / check-in.
First fix after initial RHEL6 test run:
 - Fixed major bug in hostcert renewal where key gets overwritten.
 - Turned off deprecation warnings to avoid one for import sha on python > 2.4.
Fixed the hostcert import logic further so that the renewed cert is actually accessible.
Remove the README.md to display the main README instead.
Updated output text to give a more hints on what to do with hostcerts.
Very minor output message tweak.
Make all the string quotes consistant.
Many stylistic changes to the source code to make things neater.
Added spec file.
