Interrupts Sublime Text 3's split_selection_into_lines

Usually, this should work:
1. Select multiple lines
2. Type `Ctrl+Shift+L`

The selection should turn into a selection with multiple cursors. ST3's split_selection_into_lines is called.

However, with this plugin installed, the functionality does not work. Command `followfunctionphp` is instead called (according to ST3's console), and the multiple cursors don't appear.
