added htacess commented option for font-awesome

I have two different subdomains that root at the same open cart install.
Font-awesome doesn't allow the other alternate subdomain to use the font files.

adding

<FilesMatch "\.(ttf|ttc|otf|eot|woff)$">
 <IfModule mod_headers.c>
  Header set Access-Control-Allow-Origin "*"
 </IfModule>
</FilesMatch>

fixes this.

For example: If you have an existing website, foo-company.com that roots at ~/public_html and want to install opencart to store.foo-company.com that roots at ~/publc_html/store, font-awesome will work for store.foo-company.com, but it will not work for foo-company.com/store

This edit fixes it so that icons will display correctly in both urls.
