The clear command clashes with Knausj commands

[awulkan]

Using the Knausj command clear 1 until 9 results in this error.

Saying clear one triggers the Knausj command and clears line 1 instead of the number highlighted by Cursorless.

I think probably a good solution here is to change "clear" to "change" by default, as mentioned in #66
