Restored support for apks as default arguments

[Ayowel]

Hi,

If a path is given as argument without the -p option, it is not recognised. This PR restores support for calls such as python3 stacoan.py yourApp.apk while still enabling the launch of a server by default.

This should not affect the server, however I can't test it at the moment (Address already in use error when I try to use the server, with or without this modification, even after a reboot).

Will look at the PR's when I am at home. Really, thank you 👍 for the feedback and effort put in this project. I think I will add you to the top contributor's list soon.
About the address already in use: did you get that with the executables (from the releases)? Or did you get it when running the python source code?

[Ayowel]

Happens when running python3 stacoan.py in a Kali VM from the repository's code.

On a side note, I saw you talk about your inability to use Docker as you have VMWare installed. I am in the same situation and use docker by running it from a fedora VM ; you might want to look into this.

Did you tried to drag and drop an apk on it? It seems that the arguments are causing some trouble

[Ayowel]

No, as I said I can't seem to get the web interface to work no matter what I do. I'll look into it tomorrow and find a way to fix this.

I made some changes in the develop branch. Now you are able to choose both the ports in the configuration file. Maybe try a different port and see if that resolves your problem.
I tested it on several devices and I cannot seem to reproduce the issue.
As again, really thanks for your effort! I will put you in the readme file. Shall I link your twitter or github account?

The project evolved a bit since this pull request was started. I think that the drag and drop interface is great to work without parameters. Dropping the -p tag brought up some more problems along the way so I think I just keep it that way if people want to use the command line. However, I really appreciate your contribution and suggestion.
