Hotfix to hardcode recast-detour package to previous release, as the …

…latest package that BabylonJS automatically downloads breaks the build.

+## What is recastjs ?
+
+recastjs is a port of recastnavigation and a thin abstraction layer using emscripten. https://github.com/emscripten-core/emscripten
+This port allows the use of recastnavigation in your browser using JavaScript or WebAssembly.
+
+## What is recastnavigation ?
+
+Recast is a navigation mesh construction toolset for games. 
+Recast is accompanied by Detour, a spatial reasoning toolkit. 
+You can use any navigation mesh with Detour, but of course the data generated by Recast fits perfectly.
+The crowd management module provides you with features for agents handling and behavior customization
+
+Some documentation is available here : http://masagroup.github.io/recastdetour/index.html
+
+## How to extend recastjs ?
+
+Recast/Detour can be difficult to use directly. A simplification layer is done thru src/recastjs.h/.cpp. All the functionnalities have to be exposed to JS by the IDL file. 
+Basically, that file lists all the structures, classes, methods visible to JS. The glue generation and build is handled ny make.py script. Any new functionnality should be written in recastjs.cpp file and exposed by the IDL
+For more information on Web IDL : https://emscripten.org/docs/porting/connecting_cpp_and_javascript/WebIDL-Binder.html
+
+## License
+
+Recastjs is licensed under the same terms as Recastnavigation.
