Opportunities to slim down 13.1.0 build file cruft

[Gary C Martin]

Hi folks,

I was just having a dig around in 13.1.0 build 6 for the XO-4 (using GrandPerspective), and noticed that we are still including libgweather and its 88Mb worth of Locations.xml files. I know this came up in a previous release cycle, but just want to check again that we can't save this valuable space.

Will keep looking for other file cruft to report.

Regards,
