Very long auto-generated index trimmed for use in Report Browser

The creation of a new report via the user report browser failed if there was an index with a long name (over 30 characters). The OOTB method automatically generated the prefix, but the Report editor could not handle the very long declare index name and as a result did not consider properties from the embedded pages. To resolve this, pzUpdateAssociation and pzInsertNewReportColumn have been updated to trim the prefix for the declare index to 30 characters and allow for adding a new column to the report. This work does not cover adding a new filter to the report, as that fix would require substantial changes to reporting logic.
