Migrate text layers to nodes (#1155)

* Initial work towards text to node

* Add the text generate node

* Implement live edit

* Fix merge error

* Cleanup text tool

* Implement text

* Fix transforms

* Fix broken image frame

* Double click to edit text

* Fix rendering text on load

* Moving whilst editing

* Better text properties

* Prevent changing vector when there is a Text node

* Push node api

* Use node fn macro

* Stable ids

* Image module as a seperate file

* Explain check for "Input Frame" node

* Code review
