Add revert_select_word_or_create_another_cursor and move_selection_to_next_word commands

[BuzzwordChief]

Hello,

my workflow involves heavy usage of the select_word_or_create_another_cursor command. To make this command more powerful this pull request adds two new commands:

1. revert_select_word_or_create_another_cursor: Reverts the action of select_word_or_create_another_cursor
2. move_selection_to_next_word: Executes a select_word_or_create_another_cursor and deletes the previously 'newest' cursor. It basically allows you to skip a selection.

For a better comprehension see the following demo video:
