C3134: define default credentials in a configuration file

[infotel4iarc]

If some default usernames and passwords are required, maybe they could be defined in a configuration file, and the user could be invited to change or override them them during the installation

The branch is https://github.com/infotel4iarc/CanReg5/tree/feature/C3134

Here are the point that were done :

• create a file config.properties to store the hardcoded password in the code
• add a paragraph in the instruction (see [C3134] instruction change.txt)

[fbinfotel]

The file config.properties is stored in the folder .CanRegClient

The credentials stored in this this file are used to do :

• the migration to the CanReg V5
• the creation of an adhoc database to make adhoc Analysis
• the functionality to restore a previous system

After a new installation, the user can create a new supervisor and change the credentials in the file. After that the user can create next adhoc analysis However if the user wants to migrate an old database or do a system restore or a migration he need to have the old credentials which should be the default credentials

The branch has not been merged to the dev branch, but it was rebase with the last dev branch (commit 783cd5fa). So it is fully compatible with that dev branch. If this branch is merged the user should be carefully informed of the possible issues
