Fix issue #22 with a hack
Fix issue #22 with a hack

Added two options :

* verbose -> Outputs some debug information, including the script
	source to the shell
* fish -> Enables generatio of a valid fish script instead of bash
	script

Using a toggle is the only way to fix this. Users that use fis has his
default shell, need to use it to get correct behavior. It's imposible
build a shell script that runs at bash/dash and fish at same time.
