SharedRoutine, I sent you an email about this. The pt-br.lproj folder doesn't work, only this one.

Changelog:

- Added DRAG_TO_CLOSE translation
- Added LOCK_UNLOCK translation
- Added DOUBLE_TAP_ACTION translation
- Added DOUBLE_TAP_DESCRIPTION translation
- Fixed ACKNOWLEDGEMENTS translation, it was completely wrong
- Added ALLOWED_SNAP_LOCATION_DESCRIPTION translation, it wasn't translated before
- DESIGN_VIEW translation now makes more sense
- DESIGN_VIEW_DESCRIPTION translation now sounds a little better
- LOCKED_TOP / BOTTOM / LEFT / RIGHT translation now makes more sense
