BUGFIX: Inspecting a string in Helios breaks into the debugger.

Evaluating `'hello' inspect` in a workspace would break into
the debugger. The problematic code seems to be in `HLListWidget>>refresh`
which seeks to make visible the currently selected item, without
checking whether there is a such an item. Adding an `ifNotNil:`
condition before that action fixes the problem.

Confession: I'm not aware of when exactly the `#ensureVisible:` part
gets triggered.

Tries to fix loading amber from deeply nested pages.

The default is to guess:
  - if amber path is 'xxx/bower_components/yyy',
    use 'xxx/bower_components'
  - otherwise, use 'amber_path/bower_components'

In cases when this is not enough (it should for most cases),
you can specify libs dir in data-libs attribute
of amber.js's <script> tag.
