typing.get_type_hints fails when setting the type to a string.

This has been commented in other uses, so it can be commented here too.

Also a little style update due to automatic updates.

Ref T80730, T85675

Ratings don't get sent during clicking in the rating operator, but only after hitting OK
Ratings operator doesn't remember values so it doesn't encourage same ratings for more assets.
Bump version of the addon for the release

Fix bug where QCD hotkeys would get registered twice when toggling the QCD checkbox in the preferences off and then on again.

Now sends a clear message to the UI and cancels upload
also fixes a small bug in update_down_up

Upload was wrongly detecting new upload from an asset with ID
Scenes appended had upload props on - switched to search(should be moved to window manager, similar as search results, or somehow find a way to have global for every file.)

Fast metadata - free full fix

The built-in layer button UI only draws dots if the property
belongs to an Armature, as a special behavior hard-coded in C.

This returns to drawing the UI from Python but using cleaner code.

Reduces warnings while running tests.
Also fix some descriptions with strings concatenated but without a
space in between.

When the tool is active and the blender is closed, the `GizmoGroup` type
object is freed keeping some invalid RNA members.

This is probably an internal error, but for now just work around this
error by starting the object name with '_' since "RNA can't start with
a "_",".

Add an addon-preference option to always snap on keyframes while scrubbing (Disabled by defaut).
Invert the behavior of the snap modifier key. Disabled if there isn't any keyframe.

fix: carriage return at the end of rotate_canvas.py

- Changed canvas rotation reset method (was hard to trigger with a tablet pen).
- Default angle steps increased to 15 degrees.
- HUD now appear only in active viewport as it should

This caused script_load_addons test to fail in some cases.

Multiframe is now disabled while scrubbing viewport-timeline. (like normal scrubbing does)

thanks to Robert Guetzkow.

Default import setting for models is now Append.
Fix maximum workhours rating for fast rate operator
Update categories file

The keymaps were changed in rB01d49d1542c which caused the
script_load_addons test to fail on this addon. Update the strings to the
new values.

After D10224 was committed the theme preset filenames are displayed in
the menu exactly as written in the file. This cleans up the names to
title case for display in the menu.

Importing splines from a dxf file can cause an error in the sorting
process:
```
TypeError '<' not supported between instances of 'tuple' and 'NoneType'
```

Since instances of type "SPLINE" do not have an extrusion direction,
replace the extrusion values with an empty tuple.

This currently keeps colorsettings for images to default, because we can hardly predict the names of possible colorspace settings added in variants of this or other addons.
All colorsettings settings were moved to a set_colorspace function in image_utils.py and everything happens in a try statement.
Scenes - fix link/append support and add it to UI, further support switching to scene after finishing the download.
Fix drag-drop of materials to linked objects - now theres an explanation pop-up.

- Added operators to store/restore camera rotation (handy to quickly get back to a prefered angle)
- Use a modifier key to step the rotation by a user-chosen angle
- Addon preferences UI cleanup

Rotate canvas: Quick press/release of the shortcut now align camera with Global-Z. It was only possible in free navigation before.
Timeline scrub: Now respect "limit to frame range" option if activated
Pref register: Code cleanup

Now the snap also ignores particles.
Also fix a case if user didn't fill a name in profile, now it draws at least users email.

This wouldn't previously show asset bar, now it starts search and shows assetbar.

Storing results in scenes increased file size too much. Now the search reasults are stored in window manager and thus not saved. Also this makes them shared between more scenes.
