Lua modules directory

Reviewing, hosting and thus potentially maintaining an ever growing list of NodeMCU Lua modules does not scale well for the project team. Instead, we give the community a chance - and the responsibility - to maintain a directory of Lua modules found in the wild through this wiki.

In the (hopefully not too distant) future, we will request that Lua modules to be hosted in this repository come with a test program in whatever framework we end up adopting.

A module being listed there does NOT mean the NodeMCU project team endorses it in any way.
