Fixed segfault and added support for single quotes in toxic
Add cmake module for ncursesw

Default Curses module fails to detect the wide char version of curses
when both are installed. Current module should do better.
Add wide char support in toxic (issue #440)

Set current locale, use of get_wch instead of getch for reading, use
wctomb and friends to convert back from wchar_t, link with
cursesw. Unicode support is only added to chat windows.
Remove fix_name() function

With unicode support this function is not longer valid.
