Allows for each workspace to have it's own add-ons on display.
Filtering for: Panels, Menus, Keymaps & Manipulators.
Automatically applies to add-ons at the moment.
Access from workspace, toggled off by default
once enabled, add-ons can be white-listed.

Would run register() twice causing warning with `register_module()`
which expects new classes to be defined.
Now run unregister() before re-registering.
The addons tab in the User Settings window would be empty, due to
a FileNotFound error. This error can be caused by a broken symlink,
which is now treated the same was as a file that misses its bl_info
dictionary.
Recent addons commit meant that addons would be enabled even if they weren't found.
This would give an error (which is fine), but also remove from preferences.
The addons panel draw function calls addon_utils.modules() which in turn retrieves a list of fake modules from the script paths every time. This can become costly when network paths are included for
addons. Solution is to put the scanning process into a dedicated "refresh" function and disable it in frequently called draw and filter functions, i.e. in these cases the cached addons_fake_modules list
will be used instead.
Note that this may lead to invalid addon lists if script paths are changed (which is not working 100% without restart anyway according to Campbell). For this there is now a "Refresh" operator button in
the addons preferences. If necessary and feasible such forced refreshes can be added later too.
Since the window manager is needed for keymaps this is kept as an exception.
some addons will need updating, but in every case I've seen addons should not be accessing the context while registering.
(bad stuff! - declaring the scene as a global variable - which crashes when the users loads a new file, manipulating the active object or scene... tsk tsk)
--debug
--debug-ffmpeg
--debug-python
--debug-events
--debug-wm
This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
