Fixes for Setting Null columns in Programmatic DataSets

Addresses a bug where using "[null]" in a programmatic DataSet (Using @Table) didn't work

Adds Intellij Code Highlighting for String Datasets

3.2.1

Enable Code Highlighting for String Datasets

Introduce String based DataSets

For example

@DatabaseSetup(dataset="""

""")

A more concise form than using tables, with more customisation options than using files

Improved debug-ability

Added To String methods to relevant classes
Added DataSet output when set up exceptions are thrown

Fixes a bug with Defaults

Previously it registered the "Cell" class with dbunit, rather than the value of the cell

Improved Docs

Improved Javadocs + clean up here and there
