Print - Expose all settings as config options

[MattiasSp]

The first PR relating to #1119. Also related to #785.

All current print settings are exposed as config options, letting their default values (and in some cases which values should be allowed) be controlled in the config.

Two maps for testing:

• Custom values for all new print settings
• All defaults (no config options)

I made the choice to move the default values for most variables out of their respective print controls, the print settings and the print component and put them in the index file. That way all the defaults can be seen and changed in one place instead.

Additionally, the rotation of the map is now reset after closing the print control, so that rotating a map for printing doesn't affect the regular map.

An example config with all the new options:

Works well except resolution integers cast to strings and therefore the initial state is not active:

Besides that, LGTM

Thanks @jokd, good catch! :)
