* libgweather/*.[ch]: Clean up the GPL notices and #includes.
	Remove most of the "Author: ..." comments since they're mostly
	wrong at this point anyway. The last remaining part of #538657.

	* AUTHORS: add this, containing just the original author of
	gweather applet, which is wrong, but it corresponds to what the .c
	files claimed previously, and we'll figure out who else to list
	later.

	* libgweather/gweather-location.c:
	* libgweather/gweather-location.h:
	* libgweather/gweather-timezone.c:
	* libgweather/gweather-timezone.h:
	* libgweather/location-entry.c:
	* libgweather/location-entry.h:
	* libgweather/timezone-menu.c:
	* libgweather/timezone-menu.h: Add Copyright and fix license text
	to say LGPL rather than GPL; it doesn't really matter at this
	point since the rest of the library is still GPL, but it may be
	useful in the future.
