list of dependencies in README file

[dsetrakyan]

Igniters,

I have just updated the list of Ignite optional dependencies included in
the README.txt that is shipped under “libs” folder. The file is located
under “assembly/libs” folder in our GIT repo. It looks like this file was
not maintained at all.

Please remember to update this file every time you add or remove a module.

Thanks,
D.
