Joachim Henze 3965c0c8b5 [0.4.13][SHELL32][SHLWAPI][COMDLG32][SDK] Unable to select a Zip file for sending with Common Open Dialog CORE-16908 
It "regressed" by 0.4.9-dev-632-g da6a46c6ac when zipfldr.dll got registered.
Ftr: Even without this complex fix it was possible to workaround this bug by 'regsvr32 /u zipfldr.dll'.

by porting back:
0.4.15-dev-279-g 83a9f71690 CORE-16908 [SHELL32] Allow creation of an empty CFileSysEnum
0.4.15-dev-254-g 332889b8d7 CORE-16908 [COMDLG32] Differentiate between real and virtual folders
0.4.15-dev-252-g f379a29606 CORE-16908 [SHELL32][SDK] Properly enumerate virtual shell folders (on files) as fake folders
0.4.15-dev-251-g b1003ae909 CORE-16908 [SHELL32] Update CFileSysEnum to be maintaineable
0.4.15-dev-250-g ac215455bb CORE-16908 [SHLWAPI] Fix SHRegGetCLSIDKeyW
and we also need:
0.4.14-dev-73-g 5d54b65ceb CORE-16271 [SHELL32] Add support for custom View objects defined with UICLSID
