Enum sibling presentation is not always correct

[rmouritzen-splunk]

The type attribute is not always used as an enum sibling, but is always presented as such.

Cause

This is caused by "calculating" the enum sibling pairs after the dictionary is read. This is, however, too early.

Solution

The enum / enum-sibling pairings should only be calculated for classes, objects, and profiles. This also means we should not show the enum / enum-sibling presentation enhancements on the Dictionary Attributes page.
