Ref #35
Fix build errors
Add confdir option and installation of config.json
widgets loading: remove wkline.h from widgets.c

we only use the config from the wkline var. if we need to pass something else we should make a new structure to do it
config: check object returned by wkline_widget_get_config

	also if there is a syntax error exit right away and don't print that the file was not found
