MC Upgrade - 12.0.37

Added support for selective NotesDataDirectoryOldExclude by prefixing entries with "network:" (without quotes), e.g.

*.ntf
*.log
as_*.nsf
*.dsk
cache.ndk
network:archives\*
*.tmp

The above example will exclude archives from a data folder when migrating the old data directory on a network drive to local in user context, but will not exclude them when the old data folder is on a fixed disk.

Added a new option ini:StartupLinkMode; set to 1 to "recreate" any Notes startup links deleted during shortcut removal, set to 2 to create a common startup link in any case.
If set to 1, and both a public/common startup link and user startup links are detected, only the public/common one is recreated.
If no public/common startup link is detected but multiple user links, all user links are recreated.
Note that links which are recreated are based on the newly created public/common desktop link, and no based on the previous link details.
For example, if a user has a startup link to start the basic client with the -sa option, the newly recreated link will no longer start the basic client as it is based on the link freshly created by the installer.
