This patch removes an unintended print statement (used for debugging) from the PropertyCollection code.

This patch resolves various minor issues including:

- handling of constant boolean properties
- addition of missing 'soft' xml relationships during consolidation
- better support for time dependent blocked well connection open properties
- easier access to a standardised 'source' extra metadata item
- minor improvements to the AttributePropertySet class

**This patch inadvertently included a print statement (used during debugging) in the PropertyCollection code. Please use the next release to avoid unwanted print output.**

This patch improves the handling of key clashes in the AttributePropertySet class.

This patch does not change functionality but speeds up the combined_tr_mult_from_gcs_mults() function and the underlying grid_face_arrays() function.

This change resolves issue 802 which noted that some standard property kinds were being treated as if they were local property kinds. Where the issue was having an impact, RESQML datasets should be regenerated with this release or later. The metadata for affected properties in datasets generated by earlier versions will still show them as having a local property kind.

This patch stores the normal vector of a Surface as extra metadata (if it has been established at the time of the create_xml() call).
