Possible issue with environment detection

[SelrahcD]

The use of an environment variable named SILEX_SKT_ENV for every app using the skeleton might be an issue if all apps are running on the same host but are not sharing the env.
I guess this is not the only env var used.

Yes we should make a documentation about that but yes,env variable is proper of each application, it's just a placeholder.

Then, we should parameterize the name of the two env variables

On the other hand, having a global env var is quite handy too... so that, on a same server, every app has the same env name key, that can be useful... but dangerous... ;)
