Doc and cosmetics

[Zen-CODE]

Although there are many changes here, they are all cosmetic and should not affect any behavior. I know it's not painful to make large and sweeping changes unnecessarily, but I think these are important for readability + pep8 compliance.

The types of changes and rationale are outlines below:

• Replace '''doc''' with """doc""" -> Pep8 specifies double quotes for doc strings
• Enforced 80 col line with -> Pep 8
• Removed unused import (imp) -> Redundant
• Removed assignment to unused variables -> Redundant
• Made argument passing indentation consistent
• Removed brackets around simple strings -> Redundant
• Made _read_configuration a static method as it does not use self -> good pratice? Or not?
• Replace using "args" parameter with "_args" -> Convention to indicate non-usage

Nice PR, thanks for it. I'm just not sure why was f017eb9 sneaked in?
Also can we update the tox.ini to reflect the styles you fixed?

[AndreMiras]

Why is this change in this PR?

[Zen-CODE]

Because I branched off the set_app_platform_19 branch. Will remove before I ask for a review.

[AndreMiras]

Same here, I don't think that change should be part of a "cosmetic changes" PR. What do you guys think?

[inclement]

I agree, this should not be added at all without an actual framework around what its value should be and how the user should control it. Setting it to a fixed value will work in some circumstances, but break others.

This pr was labeled a WIP because it's a work in progress. It's this not a known protocol? Not ready to be merged because i am aware of these issues. When it's ready i will remove that WIP prefix :-)

[AndreMiras]

Yep I missed that one, cheers 👍

@inclement, @AndreMiras
Okay, the PR is ready now. Re: the suggestion to update the tox.ini. Surely changing that would affect all python files. I have not combed through other files here, just changed them where I came across them in efforts to understand how to handle the 'project.properties' file when building different dists. Surely the tox.ini should only be updated when ensuring checks can be applied project wide?

[AndreMiras]

Thanks @Zen-CODE yes I was asking for tox, but I wasn't sure if you fixed per error cross project or just per file. So indeed he would complain and we can leave it as it is then.
I would be happy to approve, but it seems that we still have conflict changes on pythonforandroid/toolchain.py. At least that's what GitHub says.
Please ping me when resolved

Looking good, thanks!
Could you please wait for green build before merging? To be sure to be sure
