#9 support for multi config folders (or multi installations)

[plamen]

Because of command line options of OpenVPN, we can have different folders with config files (default config folder is saved in registry). This way we can have many OpenVPN services related to different config folders. You can have many OpenVPN installations which use different config folders.

It will be nice if we have command line parameter for config folder.

Or maybe better, option to show files from different config folders (maybe I do have config files which I do not start with services, which I do keep separately for testing or just I use them rarely)

Not sure how many people would use it, but it will make it in consistence with OpenVPN ideology.
