Generate MSO lock files when the related MSO compat. option is set

Added a new compatibility option to the Tools -> Load / Save ->
Microsoft.
When this option is set on the UI or or set in the configuration files
LO generates lock files for MSO supported file formats, similar to
the lock files MSO generates itself.
