Uses ugettext_lazy to delay translation; reworks the __repr__ method to avoid using the translated form; and changes the unicode method of the HorizonComponent class to actually return a string coerced to unicode rather than a proxy object. In the process, many more strings which had been missed have been marked for translation. Fixes bug 910297. Change-Id: Ie8d10a928b0419313e6c54b0eff7a3a37299ca83
