Fix default settings when they are boolean.

Created by: jouve

error is that enabled ||= true always evaluates to true. Change all initialization of bool settings to use the same syntax: setting = true if setting.nil?

Same as #2652 but for master.

Ouch ... I feel really stupid. I had to read it a few times until I got it ... I feel sorry for the person who proposed this fix a few days ago and it got turned down ... if you are reading this: Sorry.

For the ones who still don't get it: ;) We have boolean options which we need to set to a default value if they are not set. So if the option is nil we assume it is not set and set a default value. If it is false we assume it was set deliberately, so we leave it. Can anyone see it now? ... I'll tell you: We use the ||= operator which will assign the value on the right if the left-hand expression evaluates to false. In our case we would set the default value regardless whether the option was nil or false thus overwriting a user setting. (btw that's the reason we were getting those "I disabled Gravatar, but it isn't really disabled" issues )

So now we explicitly check and only overwrite boolean options if they are nil. Thanks again @jouve.
