compile_dir/2,3 produces modules with incorrect output

[acammack]

Modules produced with compile_dir/2.3 return {ok, iolist()}, making them incompatible with the custom_tags_modules option. This occurs on the latest master, but not stable.

$ cat helpers/broken
This helper is broken

$ cat foo.dtl
{% broken %}

$ erl -pa ebin/ deps/erlydtl/ebin/ deps/erlydtl/deps/merl/ebin/
Erlang/OTP 17 [RELEASE CANDIDATE 2] [erts-6.0] [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.0  (abort with ^G)
1> erlydtl:compile_dir("helpers/", helpers, [{out_dir, "ebin/"}]).
{ok,helpers}
2> erlydtl:compile("foo.dtl", foo, [{out_dir, "ebin/"}, {custom_tags_modules, [helpers]}]).
{ok,foo}
3> foo:render([]).
{ok,[<<"{ok,[<<\"This helper is broken\\n\">>]}">>,
     <<"\n">>]}

Ah, so that was the reason for having compile_dir templates behave differently from that of regular templates. (this change was introduced in commit 0b61b69).

I'll look at how to best resolve this.

Thanks! This works like a charm.
