PlatformIO projects get re-initialized

[giapoldo]

I opened ST by dragging a PlatformIO project folder to sublime launcher (on macOS Sierra, but happened on OSX El Capitan as well). The project uses a different environment than the last build done with Deviot (Deviot seems to remeber the last environment used), so upon build, it initialized the project again, effectively adding the old environment to the project.

Maybe Deviot could check for a platformio.ini file first and set the environment automatically?

Thanks!
