Create data dictionary functionality

It would be nice to have a way to auto create data dictionary just as we can choose to create ER diagram.

Something like being able to generate a pdf or so that looks like

```
TABLE_NAME

FIELD_NAME FIELD_TYPE FIELD_LENGTH NULLABLE FK PK COMMENT
```

Something like

```
EMPLOYEE

FIELD_NAME FIELD_TYPE NULLABLE FK PK COMMENT
Id Guid False False True free form comment
FirstName Varchar(20). False False False Employee first name
...
...
```
