Adds `ui_text_skip_selection_for_next_occurrence` action and related implementation to text editor.
This action is bound `Ctrl+Alt+D` shorcut.
Used in conjonction with `ui_add_skip_selection_for_next_occurrence`, it gives the user the ability to select many occurrences of a selection
and avoid some of them.
Used without a previous selection, the action jumps to the next occurrence of the current word under the caret.
