SchemaSpy 1.5.1 released

Now displays two versions of the main relationships graph: a smaller 'compact' version and a large full-size version. The compact version should make it easier to get a 'big picture' view of the relationships.

Now takes advantage of the GraphVis dot 2.6 ability to point to the East/West center of a node if running dot 2.6 or higher.

Figured out a way to have the graph point to the appropriate portion of the main table in the table detail pages.

Introduced a new anomaly: Columns whose default value is the word 'NULL' or 'null', but the SQL NULL value may have been intended.

Index sort order now relates to the column, not the index.

Added some instructions on the format of ConnectionSpec in the .properties files.

Added table/column/index IDs for those databases that give error messages without names (e.g. DB2).
