Release/2.0

[e11sy]

This PR is related to #75 issue This PR is result of global work on List 2.0

Problems

• Could not use List or Checklist data format for Nested List
• Can not use cheklist as style of the nested list
• Data model has no place for meta (e. g. checked field for checklist)
• Nesting is not customizable
• Can not start ordered list with custom variable
• Can not change counters for ordered list
• Can not split list on enter in the empty item in the midle of the list
• Does not support backspace on the start of the first item
• Nesting works unexpected sometimes
• One file architecture
• Shortcut fails to make defaultStyle effective
• defaultStyle is not respected by toolbox

Solutions

• Implement checklist as style of the nested list

• Support new data model with meta attribute for each item:

  interface ListItem {
  content: string;
  
  meta: OrderedListMeta | UnorderedListMeta | ChecklistMeta;      // meta should depend on list type
  
  items: ListItem[];
  }

• Separate List rendering and tabulation (rendered should render items and wrappers dependant on list style), tabulator should handle keydowns and work with editor events
• Rerender list, when style changed
• Export all list styles to toolbox
• Implement data converter from old List and Checklist formats to new Nested List
• Support nesting customisation by maxLevel config option
• Support <ol> attributes, in config (such as type, start)
