This shifts to use the model-view-controller pattern for the list of addons,
and moves to using a full model class rather than an indexed array for the
data storage and management. This enables much more information to be stored
as part of the new AddonManagerRepo data type. It now wraps the Macro class
for macros, supports Preference Packs, and provides access to the Metadata
object.
I believe this code is currently incorrect, as it makes references to code outside the "if code" block, where it can not be ensured that code is a string. Moving the code processing into this block avoids this issue.
I experienced a stuck Addon Manager, which was caused by an exception
```
File "/usr/share/freecad/Mod/AddonManager/addonmanager_macro.py", line ..., in fill_details_from_wiki
FreeCAD.Console.PrintWarning(translate("AddonsInstaller", "Unable to clean macro code: ") + code + '\n')
TypeError: can only concatenate str (not "list") to str
```
which is fixed by these changes.

Update formatting in compliance with pep8 with the following exceptions:
* truncate to 120 characters in line
* prefer double quotes `"` to single quotes `'` in strings
Correct crash when Macro description is not reachable
Python crashed when under proxy - Macro list is charged - Proxy is undone ( internet connection lost) - Try to load macro description (u=None)
Add Proxy setting in Addon Manager Option UI
Correction of SSL context
Replace ssl.Purpose.CLIENT_AUTH by ssl.Purpose.SERVER_AUTH as context for a client
Add configuration of proxy setting UI
Add proxy management by urllib
Read the metadata __Files__ for macros from git and install or remove
files listed there.
__Files__ must be a comma-separated list of files to be copied alongside
the macro. Their path must be relative to the macro (*.FCMacro file)
and not to othe root of the repository. Each file can be prefixed with a
subdirectory.
Separate the Macro class of the AddonManager into addonmanager_macro.py
to prepare for future support for dependent files for macros from the
git repository.
