Support per-document options

[Ashod]

This adds support for per-document
options, such as enabling/disabling
printing, copying, exporting, etc.
and adds the ability to set a watermark
and other security settings.

These option/settings can be modified
by the document owner. The document locking
logic is also included as a form option to
make it homogeneous with the others.

The options are hidden by default, in a collapsed
section. They are never shown to user without
the ability to modify them.

Hello @Ashod ,

you have made a lot of code changes, witch brings a lot of complexity. All these options should also work with moodle groups and groupings.

Do you have tested all these settings with moodle groups and/or groupings mode too?

Thanks & Greetings,
Michael
