Add btcgpu.org to HTTPS-Everywhere

btcgpu.org is BTG's official website, which support https but use http by default.

I hate that.

So, let's go.

Create one XML file with the content below:

<ruleset name="btcgpu.org">
    <target host="btcgpu.org" />
    <target host="www.btcgpu.org" />

    <rule from="^http:" to="https:" />
</ruleset>

Then pull request to EFForg/https-everywhere:

Create btcgpu.org.xml by ivysrono EFForg/https-everywhere

At last, users of HTTPS-Everywhere will auto visit https://btcgpu.org/ with next release.
