Add compression option to changelog
* Add support for creating resources inside configuration files. This makes
it possible to create simple config files that have fwup variable
references in them without requiring a separate script.
+ * Add -1,-2,-3,...-9 to tune the compression. The default is -9, but on
+ massive archives, this is really slow, so you can pass a lower number
+ to speed up archive creation.
