Add Fetch from BSB button to admin lesson editor; v1.1.36

Adds a one-click "Fetch from BSB" button in the lesson passage text field
that calls the BSB API and overwrites the field with verse-numbered text.
Also fixes reference parsing to tolerate leading book abbreviations like
t:1-2 or col:1-2 by stripping letters before the chapter:verse pattern.
