RY does not read in property values exactly mating the requirement ID

For properties, RY removes the requirement key of the current line, if it is the first characters of the line, and removes the whitespace of the remainder.

New implementation:

• Detect if the requirement link was alone in its cell, and only remove it if it was alone,

• Keep the requirement link if the requirement is defined outside a table,

• Keep the requirement link if the column is defined with RY Property = property.
