Card data in images (start)

* Add uuid implementation

* Simplify uid implementation

* Check for uid conflicts upon adding/copying cards

* Remove unnecessary checks

these are already checked as part of the first loop, since they were added to set.cards

* Implement card linking

* refactor to avoid triple loop

* Start link visualization

* Continue link visualization

* formatting

* add missing locale entries

* improve layout

* improve UI refresh

* copy links when copying cards

* implement second face editor

* refactor using macros

* get references

* pasting multiple cards and links

* start refactoring editors

* continue refactoring editors

* continue refactoring editors again

* finish refactoring editors

* refresh card list on link editor event

* tweak event handling

* Add insert_image script function

* change parameter type

* add script functions to get cards

* add dimensions_of script function

calculate both dimensions simultaneously while rendering the image only once.

* save value even if not editable

* add get_mse_locale script function

* Change zoom scale choices

* bug fixes

* Scale symbol spacing with font size

* sync locales

* standardize line ending

* handle links in new_card

* initial
