Update/autogenerate list of examples

http://nitlanguage.org/examples/ points to only very few examples. Another few are relatively easy to find in NIT/examples and NIT/contrib

Some very important examples though are hidden in lib/* - who would search for lib/android/examples/src/ui_test.nit or /lib/app/examples/ ?

Hi @rgh36167,

I have something I'm working on about this problem (https://github.com/Morriar/nit/commits/examples). The idea is to extract all examples found in the repository and to display them in nitdoc and nitweb.

I leave this issue open, you will be notified once my branch is merged.

Thanks for your suggestion!
