Draft: Improve usability of vector layers and add multi-selection
Just throwing a few ideas in the works here for Vector Layers. What I've changed is as follows;
- I have merged in the latest commits from the master branch. Included in this was enabling multi-selection for paths. I've made the 'Path to Vector Layer' option multi-path aware by just merging the constituent paths
- The new 'hidden item' mechanic is used to create and attach a hidden path for each vector layer. This hidden path is edited along with the layers instead
- When a vector layer is selected or a path, the currently active path is changed in the user interface
