[law-lee]

When i compile this module into nginx-1.6.3, it causes an error below:

../lua-upstream-nginx-module/src/ngx_http_lua_upstream_module.c: In function ‘ngx_http_lua_upstream_get_servers’:
../lua-upstream-nginx-module/src/ngx_http_lua_upstream_module.c:179:22: error: ‘ngx_http_upstream_server_t’ has no member named ‘name’

I've tried different versions of this module, it is the same error. nginx-1.6.x should still be supported. @agentzh Could you help me out here ?
