Comment (by m7.thon@…):

 * New simplified Portfile to allow compilation with lua 5.3
 * patch-lua53-compatibility.diff no longer needed

 I just realized that it is sufficient to compile with lua 5.2
 compatibility mode by defining {{{LUA_COMPAT_5_2}}} (didn't know that this
 needed to be explicitly enabled)
