~/.polymorph dir //WIP

[XaviTorello]

Use ~/.polymorph dir

// Do not merge, the idea is to integrate it into a devel branch and keep working on it, but I can just PR to master.

This improves Polymorph to be able to store all files (conditions, templates, temps, ...) inside a $home based polymorph directory.

By default this points to ~/.polymorph, and at init time it ensures that the needed structure exists

In this case, we validate:

- ~/.polymorph
- ~/.polymorph/conditions
- ~/.polymorph/templates
- ~/.polymorph/conditions/executions
- ~/.polymorph/conditions/postconditions
- ~/.polymorph/conditions/preconditions

New settings class supports us to set library based properties and prerequisites.

It adapts all IO operations to use new settings.paths

It also provides a new way to perform hot module loading based on the imp library, see new method utils.import_file

Additionally, templates save process ensures that .json extension is included, and dumps the template to the templates folder ~/.polymorph/templates.

WIP, some things to do

• [ ] validate and test using all support py versions (2.7, 3.4, 3.6, 3.7, ...)
• [ ] review pcap creation and loading
• [ ] analyze other possible IO
• [ ] test Windows, MacOS, ...
• [ ] manage lack of permisions to write on home
  • go to /tmp?

Will fix #2
