(svn r1616) Introduce ttd_strlcat() and use it to de-uglify some piece of code in misc_cmd.
While here rename the len parameter of ttd_strlcpy() to size, because it is a buffer size and not a string length.
Also add -Wwrite-strings to the Makefile, because the above mentioned piece of code was the only part which triggered this warning.
