Find easy way to install workflow during development

[maltsev]

Currently during the development, I use a custom make command to copy the executable to the workflow directory to test it. This works well, but since the Alfred workflows directory might have a different path on other developer's machine my command won't be really useful for them.

We could use alfred CLI tool and its link command for that (thanks @nikitavoloboev for the suggestion!).

Another solution is to find a way to determine a path of the Alfred workflows directory. Then my script could be used by other developers. Though, by now I've found no easy way to determine the path.
