Added a few more mime-types that should be compressed.

[Thorium]

The default list of compressable MIME-types is quite small:

The types added in this PR are:

• SVG images that are XML-files. Those are common and large text files
• YAML-files. They are text-based resources, like dictionaries.
• Uncompressed truetype-fonts, they can be large and they will compress quite well.
• Default settings from Azure CDN compression enabled MIME-types.

Awesome, thanks a lot!
