The Access Violation while closing Notepad++:
https://github.com/notepad-plus-plus/notepad-plus-plus/issues/3961
could be due to SCN_UPDATEUI sending after NPPN_SHUTDOWN, that makes
plugins treat SCN_UPDATEUI on the released handle.
To avoid such situation, once NPPN_SHUTDOWN has been sent, no more
message will be sent to plugin.
Fixes#3961, fixes#4021
1. Fix shell extension registration error (due to notepad++.exe has not
yet been copied)
2. Fix themes' absence after installation (one variable depends on
its initialization in mainSection)
