Fix build issue due to previous commit

Revert in rB05dddb71b098 did a poor job and left some
rubbish.

Revert "Info Editor: move to c++"

This reverts commit 9cce18a5858cb93da626f5f0fd7e09cd66637e05.

rB9cce18a5858c broke the build in unforeseen ways, not easily fixable.
revert for now, so master will at least build again.

Fix various Blender 3.0 versioning issues

This changes the following items:

- package name is now `blender-3.0.0-git.09eb04c0a865-windows64`
rather than `blender-3.00.0-git.09eb04c0a865-windows64`
- Fix version resource for blender.exe not building
- Data directories are now `3.0...` rather than `3.00....`
- User prefs are now in:
`c:UsersusersAppDataRoamingBlender FoundationBlender3.0`
rather than:
`c:UsersusersAppDataRoamingBlender FoundationBlender3.00`
- Updating startup & preferences from previous release
has a special exception for 3.0 to check for 3.93 and older.

deps_builder: Bump download time out to 30 mins

The timeout was set to 60 seconds, which was problematic
for some of the larger files like boost from the blender
svn mirror.

Fix: Missing GeometryNodeCustomGroup

This is a minor change to add some plumbing code
to support custom geo nodes. This is working the
same way as the custom cycles and compositor nodes.

An example add-in is attached to D10784

OSL: add basic OSL shader template

Add a basic OSL shader that shows how inputs
and outputs work and do some simple math with
them.

This template is a happy medium between the
templates we already ship, empty_shader is a
little too bare, and the other templates are
a little "too much" and you end up having to
delete a whole bunch of stuff.

a great starting point for some experimentation!
