[r100/101] "Set layer effect enabled" display bug

This bug appeared in r100 and made it through to r101. The "Set layer effect enabled" action is displayed like this:

1} layer <layer name or number here> effect Enable

or (if the effect is being disabled):

1} layer <layer name or number here> effect Disable

The action works correctly, though.

Reproduction steps:

1. Start a new project or open an existing one.
2. Add any effect to any layer.
3. Create a "Set layer effect enabled" action.

Thanks, should be fixed in next build.
