Add gzip compression for directory listings and text assets served over HTTP.
This reduces the rclone repository file listing from 40 kB to 8 kB and reduces
the rclone MANUAL.txt from 2.7 MB to 700 kB.
This makes listings and assets served across the network load faster.
The compression level of 5 should be a good balance between size and speed.
Add AU East 1, EU South 1, JP Central 1, UK East 1, and US Central 1
regions and endpoints for Fastly Object Storage.
Also sort the entries alphabetically.
