[Glass] gsApplicationTools global environment variables

[Sebastian Heidbrink via Glass]

Hi all,

I am using gsApplicationTools to maintain my maintenance and ZincRest gems.

For testing purposes I setup a second stone and its gemServers would not 
start.
It took me a while to realize that during the first install of gsDevKit 
some environment variables for logging, the extend and such seem to be 
global.
This results in weird situations where e.g. the logs reference the wrong 
extend and log files path in the headers, the gem server start scripts 
call into the wrong stone and such...

I wasn't able to find any issue reports on that on github, and wonder if 
somebody else had these issues, too or if that is meanwhile already fixed.

Thanks
Sebastian
