Install issue on Windows 10

[JMezquerro]

Hi,

I get an error installing COSMOS in windows 10, either using the .bat file or through command prompt (gem install cosmos). I've install COSMOS in the past succesfully, the issue raised ~2 days ago. This is the log recevied in the command prompt:

"Downloading 64-bit Ruby
Exception when calling "DownloadFile" with the arguments "2": "Canceled the request: Unable to create a secure channel
SSL/TLS."
In Line: 1 Character: 1

Github recently made a change that disallows any clients not using TLS 1.2 (crypto-removal-notice). Edit the Installer script and change the powershell download line to the following.

powershell -Command "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; (New-Object Net.WebClient).DownloadFile('!PROTOCOL!:!RUBY_INSTALLER_PATH!!RUBY_INSTALLER_64!', '!COSMOS_INSTALL!\tmp\!RUBY_INSTALLER_64!')"

The new code is the explicit setting of the SecurityProtocol. We will update the installer script soon.

I just pushed this change to the installer script. You can get the new one at:

https://raw.githubusercontent.com/BallAerospace/COSMOS/master/vendor/installers/windows/INSTALL_COSMOS.bat

We still need a different fix for Windows 7

Now it works perfect again! Thank you very much for your great work with COSMOS!

I just checked in a change to fix Windows 7 as well.
