Added connector automatic false setting when converting conditional connectors from decision nodes
- Refactoring of the EPC to Flowchart AdoScript conversion script, to make sure that conditional connectors are converted properly.
- Each connector's attribute "Expression result" is set on "true" by default, so when a decision results in false, we can write in the EPC connector's "Description" attribute the string "false". When the EPC will be converted to Flowchart, that connector's "Expression result" attribute will be set to false, taking the value from the EPC connector's "Description" attribute
