Fixes the reg class key order for FS items. The existing code was close,
but for some reason used `//` as the path separator for SystemFileAssociations!
- Fixed SystemFileAssociations.
- Swapped the order of `*` and `AllFilesystemObjects`. This is the documented
order and can also be observed in Process Monitor.

- Removed `(..., L"%s//%s", extension, wszClass)`, this does not seem to be
a valid thing (`.TestAAExtWeird` in my tests).
- Adds the `Unknown` class when appropriate. Not adding the `openas` verb
to `Unknown` rgs registration now to mimic Windows, because ROS
`CDefaultContextMenu` lacks verb de-duplication and the menu would end up
with two "Open With" entries. This just uses `(cidl == 1)` to simulate
Windows, while Windows on NT6 uses `MultiSelectModel=Single`, a NT6 feature
not implemented in ROS.
- The class order for folders was wrong and is still "wrong" in this PR,
but I chose to use the Windows menu display order until the exact mechanics
required in `CDefaultContextMenu` can be understood.
- Extracts the extension from ANSI PIDLs.
Some style-improvements I wanted to apply before a planned backport.
E.g. The biggest source-file CDefView.cpp in [SHELL32] can be shrinked considerably by stripping some outdated
comments from 10 and more years ago, when this class was still non-OOP and named ShellView.
Less excessive line-lengths also here and there.
In case it is not obvious when reviewing: In the beginning of CDevView.cpp in the declaration-part I just
reduced the indentation-level by 4 spaces for a big block.
Some shell classes were touched during 0.4.15-dev'ing for fixes like the 'unkown'-typo in
0.4.15-dev-6323-g 3854a5d8e9 for example
or missing \n were added to dbgprints like in
0.4.15-dev-4492-g 03422451b3
Touched again here, because I want to port those improvements back,
but don't intend to increase the size in older releases.
The commit looks big, but does consist solely of trivialities.
There is no functional change in this commit, aside the logging ofc.
