Fix forceSsl exceptions

[chrisrowe]

This ensures Patrol starts with a baseUrl containing the schema (and includes a port if used) before trimming/replacing http: and avoids it throwing a FILTER_VALIDATE_URL exception. I also added the available override setting to the readme.

I also remembered after digging through Yii's Request.php that both serverName and hostInfo are susceptible to Host spoofing by passing a header. Is this something primaryDomain is designed for, to prevent cache poisoning attacks?

@chrisrowe Thank you!

I've been lagging behind on Patrol maintenance, your help is much appreciated.

Primary domain is used in routing but for a slightly different purpose than SSL alone.
It let's you redirect to a specific domain if your site/app can be accessed via different domains.

@selvinortiz Thanks, any idea when you'll be cutting a new release for this?

@chrisrowe Sorry about the delay, Chris. I'll do my best to cut a new release before the weekend.
