Refactoring the Python detection.

[m4rcu5]

On Gentoo (and the Arch Linux machine I had access to), the following condition is never met.

        if(out[0] > 0):
            self.check_sym_link()

This refactor will check the version, and if it does not match 2.x it will try a python2 symlink, if this still does not work, errors out with the download dialog.
Also stores the symlink name in the configuration.

Would someone be able to test the OSX implementation and the if(not external_bins): statement?

For me this fixed my issue reported at #117

Though this will not fix all my issues;
the boards.json file contains:

Unknown option: -f
usage: /home/mvandam/.config/sublime-text-3/Packages/User/Deviot/penv/bin/python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.

To fix the boards.json, delete it and restart sublime, it should re-generate that file with right data.

Let me know if after it's fixed

I have pushed some fixes and improvements related to the issue you have reported, my fix was simplier: 64ae87e I've added new options and improvements. (see #117)

I've test this in Ubuntu and Arch Linux but not in OSX, I'll try to do it soon

Thanks for your help!

Hi @gepd, the issues as reported in #117 are fixed (will confirm there was well). I am not following along on the check_symlink(), as I would expect all moderm OS's to symlink Python in any case. This morning i was thinking of even expanding it and try all the possible options (in PATH, python, python2, python27).

But if it works, it works 😃

Yes, I think it could be improved, until now anyone has reported a setup in python27, but will let in my task list to do, possibly to the next release
