evas textblock: handle ellipsis when text's height exceed its area by "br"
Summary: Textblock's ellipsis feature only worked when text's width exceeds its area. So, it didn't work when text's height exceeds its area by "br" tags. This patch will do ellipsis when only ellipsis=1.0 is set. @fix Test Plan: make check Reviewers: herdsman, raster, cedric, jpeg, sohyun Reviewed By: raster Subscribers: woohyun Differential Revision: https://phab.enlightenment.org/D5412
