Bug fix for missing dignities.

**Changes:**
* Renamed Pars Fortuna to Part of Fortune / `chart.PART_OF_FORTUNE`.
* Added Part of Spirit as `chart.PART_OF_SPIRIT`
* Added Part of Eros as `chart.PART_OF_EROS`
* New setting `angle_precision` defines rounding for formatted angles
* New boolean attribute for traditional planets, `in_sect`, based on Hellenistic sect calculation

- New setting: `output_typical_object_motion` modifies stringified chart object to only output phase if atypical of its default motion.
- Spanish translations available as `es_ES`.
- Documentation reorganized.

Explicitly include .mo files for packaging.

- Localization added with Brazilian Portuguese as its debut translation, courtesy of nodbr.
- Chart weightings are now wrapped in their own class, so instead of, for example, `natal.weightings['elements']` you can now access it via `natal.weightings.elements`.
- Stringified chart objects now show movement (direct, retrograde etc.)
- Object & house JSON show decan info.
- Sign JSON includes modality & element.
- Fixed an issue with the swisseph file path not always being set, with unpredictable results in some use cases.

- Fixed broken `add_filepath()` test
- Added `date_time_ambiguous` flag to `Subject` class
