Updating module Files to a fully functional zk 1.3.0-6 version

Situation:
----------
  - Module Files on zikula-modules does not work on a zikula 1.3.0-6. It has not been maintained for a year.
  - Agora team has this module in production sites with zk 1.3.6 (https://github.com/projectestac/agora).
  - Agora version is running in their multisites, but have diferent problems in a standard install, because their last hacks.

This work:
----------
  - I've forked zikula-modules/Files to intraweb-modules13/Files to fix these problems.
  - I've updated the code with all the changes made by Agora team this year.
  - I've fixed diferent problems: dependence introduced with multisites, with Agora functions and with catalan language.
  - I think we have a fully functional zk 1.3.0-6 version now.

Options:
--------
I will try to continue the module maintenance module. I think there are three options:

  1. Continue to maintain the code only in intraweb-modules13. Maybe you need to delete the no-functional repo zikula-modules/Files.
  2. Continue to maintain the code also in zikula-modules. I'll send PR for updating...
  3. Continue to maintain the code in zikula-modules. Then I volunteer for maintenance.

Awaiting your answer...Thanks for your work,

Joan
