Remove ForceHttp option

Initially I wanted to make it configurable to choose either HTTPS (preferred), or HTTP, depending on user choice.
I strongly believed that it WAS possible without much headache, and solve many older Mono issues without any strong code drawbacks.
However, Volvo proved me wrong yet again, as it seems that using HTTP just like that for accepting a trade makes it impossible, and that's ONLY because we're using HTTP and not HTTPS, even if all other data, including referer, post and request, looks exactly the same.
It's quite sad that I must remove this option, but I literally discovered that switching this to true makes accepting trades impossible, and that is beyond the point I can accept, as user could switch this to true when he doesn't need it, and limit program functionality without even knowing that this is the cause.
Everybody using up-to-date Mono should have no issues using HTTPS, even legacy TLS 1.0, so hopefully this won't hurt that marginal percent of users that had this set to true in the past. It was mentioned in the wiki that this option might disappear later on, and this is the moment when it doesn't only should, but MUST, disappear... 😢
