Fix issue when using word-cache: Make sure we have a 'last' word
before trying to free it, else we segfault. Fix compiler warnings wrt const vs non-const of Evas_BiDi_Props. Fix formatting and remove whitespace also. NB: The major change here is in evas_font_word_prerender wrt freeing the 'last' word of the cache. SVN revision: 53166
