MC Upgrade - 12.0.41

Fixed an issue where InstallFinishedTimeout was not honored when displaying the IconFinder / a success message dialog when running as SYSTEM

Added a new feature to display an optional logo.png/logo.gif (png takes precedence if both exist) at the top of upgrade messageboxes (except the IconFinder, as it would become too large)

DLL files in CopyTo... folders without the overwrite suffix will now also be overwritten if the source file is newer than the target file

EXTMGR_ADDINS, AddinMenus, and NSF_HOOKS notes.ini entries are now processed as follows:

- if notes.exe is found in NotesProgramDirectoryNew, all entries are removed for which the bitness does not match
- if a pmc64(.dll) entry is found, but no such binary, and a 64 bit pmc.dll binary exists, the entry is changed to pmc.dll
- for entries which point to a binary which exists in both the program and data directory, the binary in the data directory is deleted
- in case multiple entries point to a MarvelClient binary (whether Essentials or licensed), only the newest binary and corresponding entry are kept
- in case entries point to a mix of MarvelClient Essentials and licensed binaries, the newest licensed binary is kept (even if older than the newest Essentials binary)
  (If the common data folder contains pmc_data.dll or pmc64_data.dll and a corresponding entry exists, the newest Essentials binary is kept)
- entries pointing to non-existent binaries (in shareddata\common, program, or data, or (accessible) filename) are removed
