Add the Lua dependency inside the project

For lua to be easy to use, just unpack the 1M source files in a vendor folder for all third party's libraries. Inside Vivy you should include the "Lib/Lua.hh" header and everything should works fine. Also create precompiled headers for the lua library and reuse them in Vivy.
