Teaching tool and dispatching

[maeyler]

Another request from Prof Oğuz Borat: Teaching Arabic with samples from Quran

Now we have a folder of lessons: ders/*.html

The dispatching rules in index.html were extended:

• '#p', '#v' => reader.html
• '#r', '#topic' => mujam.html
• '#b', '#w', '#t' => /Rehber/finder.html
• '#d' => ders/*.html To open ders/01.html use https://okuyun.github.io/Kuran/#d=01
