Add lunr library
This is as far as I can get with Lunr

Problem, of course, is that Lunr create a really huge object that
even crashes the desktop browser.  Great project though.
First working websql db
Updating db works
All functions working in websql
Remove the sql file

Not necessary, as data is loaded from the regular json file.
Update README for this branch
Clean up code
Improved search and snippets - not perfect, though
Put thumb index (sections) into an array
Port all favorites to web sql
Complete merge from web sql
