Speak accented letter names as base-letter name plus accent name, using a table of Unicode characters up to U+17F. Added $accent attribute for *_list files, meaning "speak as base-letter name plus accent name". Added accent names to several languages *_list files. Added language option to allow vowels to merge between words (used for lang=TA). git-svn-id: https://espeak.svn.sourceforge.net/svnroot/espeak/trunk@153 d46cf337-b52f-0410-862d-fd96e6ae7743
