[UI] Roles - Generating from edm

[TIVMOF]

Right now roles can only be created manually with a roles file. However we have exact number of roles that should be created and semi-exact names for the roles - NameOfTheEntotyReadOnly and NameOfTheEntityFullAcces. So they could be generated.

Make an option upon generating from the edm to choose if you would like to generate the default roles. When selecting that option roles files for each primary entity with the two roles from above should be generated. Then they should be added in the security tab of the respective entity.
That way roles will be directly specified lowering the risk of mistakes.
