Add possibility to ignore schema names when comparing two schemas

**Is your feature request related to a problem? Please describe.**
When comparing between two schemas with the tool "Simple compare", it shows differences because of the name of the schemas are different, althought the DDL of the tables are equals.

**Describe the solution you'd like**
I would like to have the possibility to explicitly tell the tool to not include the schema name, so that, the DDLs are considered equal. Maybe a checkbox "Ignore schema name"

**Additional context**
We have a Database with two equal schemas (Every schema is a stage)
