Add "Share My Screen" to RescueAssist

We are converting our support team from using GoTo assist to RescueAssist.

The updates you have made in the last month and a half are phenomenal, great work.

The feature we need to see from GTA in RescueAssist is the ability for the attendant to share their screen with the customer/client. This feature allows us to deliver 5 Star service by quickly demonstrating proper software workflows, and allows us to upsell new features and modules by having a technician give a quick demonstration on their machine.
