ocf_ssl: update incommon intermediate for sha2
ocf_www: use appropriate ssl chain file

We were using the bundle before, i.e. sending the server cert twice.
It worked but was unnecessary.
Rename blight -> ocf_wiki
ocf_wiki: remove gitweb config
ocf_www: quote mode appropriately for linter
Use ocf_ssl module to provide ssl for more modules

We're still hard-coding a lot of FQDNs because I don't want to spend the
time to turn the vhosts and config files that reference them into
templates and use $fqdn right now.

Eventually we should, though.
