Offline mode

[DominiqueManzi]

From XR Operator Advisor version 2.5.x, the offline mode has been changed as follow:

1/ no need anymore to create a folder in offline mode, just download the room and find it in offline,

2/ you will have to select an expiration date (in number of days from the download date, 1 or 7 or 15 or 30 days): the room will be automatically deleted at expiration date,

3/ you will have to protect the room with a password (with digits, at least 8 characters, upper and lower case, and at least 2 different characters).

This modification has been implemented as a cybersecurity requirement and to avoid unlimited usage of XR Operator Advisor with no valid license.
