Add syntax_tools to erlang dependecy for epp_dodger

[platinumthinker]

I see:

** Reason for termination == 
** {'module could not be loaded',
       [{epp_dodger,parse_file,
            ["/home/thinker/develop/thinker_home/deps/cowboy/src/cowboy.erl"],
            []},
        {sync_scanner,'-who_include/2-fun-0-',2,
            [{file,"src/sync_scanner.erl"},{line,663}]},
        {lists,'-filter/2-lc$^0/1-0-',2,[{file,"lists.erl"},{line,1284}]},
        {sync_scanner,process_hrl_file_lastmod,4,
            [{file,"src/sync_scanner.erl"},{line,650}]},
        {sync_scanner,handle_cast,2,
            [{file,"src/sync_scanner.erl"},{line,225}]},
        {gen_server,handle_msg,5,[{file,"gen_server.erl"},{line,599}]},
        {proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,237}]}]}

for lastest sync lib

Thanks. I'd been on and off with this in the past, because of the apprehension of application:start(qdate) giving the "syntax_tools not started".
