Setting the mime type in your Web Server for Apollo applications

From the Apollo Release Notes:

In order for client browsers to recognize an Apollo application when being downloded, the Web Server hosting the Apollo applications needs to map the following mimetype
to the Apollo extension “.air”. For example, for an Apache Web Server you will add to the AddType section:
AddType application/vnd.adobe.apollo-application-installer-package+zip .air

Note, you can do this in the web server config, or if using Apache, in the .htaccess file.
