This adds support for preset categories.
Preset category is actually a subdirectory under ~/.config/blender/2.82/datafiles/sverchok/presets/. Only one nesting level is supported.
Presets that were not categorized stay in special category named "General". User can not remove this category or create another one with the same name.
Active category is selected from the drop-down menu in the Presets panel.
Category can be created from "Manage presets" mode. Empty category can be removed.
Preset can be moved from one category to another from "Preset properties" dialog.
