Honor the options type when exporting bundles.

Honor the options type when exporting bundles.

Improve the way booleans, int and float 
service options are exported in the bundle.

Also fix a bug with boolean options and
checkboxes in the inspector:
- set an option to true and save;
- restore an option to false and save;
- the option label says "false" but
  the checkbox is switched back to true.

We might need to improve the way boolean options 
are normalized before they are stored in the db. 
They can be booleans or strings, I guess based 
on the code path that executes the 
service.set('config') call. Added an XXX comment.

QA: 
- try what described above in the inspector;
- set/unset/restore to default options,
  including booleans, integers/floats and 
  strings; export the bundle; ensure it works.
