Fix for bad placement of config file.

Fixed by changing the Output Path of SteamBot to <projectroot>/Bin/<build_config>. Where <build_config> is either Debug or Release. This also includes a copy of ``settings-template.json`` in a Release folder in the same place. This means users won't have to copy their ``settings.json`` somewhere else.

Also a much needed update was done to README.md and the old (hopefully unused) file ``SteamBot-2.sln`` was removed. I don't know if anyone was using that.
