Title: always print error backtrace

When an error happens in the repl you get a full backtrace:

```
$ julia -q -L program.j
julia> test()
type CompositeKind has no field __pl_style_func
in set at subgrid.j:690
in page_compose at program.j:1207
in show at program.j:1220
in test at program.j:1441
```

But when evaluating a cmdline expr, you don't:

```
$ julia -q -L program.j -e "test()"
type CompositeKind has no field __pl_style_func
```
I'm not sure if this patch is the right approach, but it passes the test suite, and appears to do the right thing:

```
$ julia -q -L program.j -e "test()"
type CompositeKind has no field __pl_style_func
in set at subgrid.j:690
in page_compose at program.j:1207
in show at program.j:1220
in test at program.j:1441
in process_options at /Users/nolta/julia/j/client.j:131
in _start at /Users/nolta/julia/j/client.j:201
```
