Advanced Settings for RDP connections

Created by: jwhipp

Please give us some details about the systems you are using:

• Client (OS name and version): Ubuntu 14.04, 16.04, 16.10
• Remmina version (remmina --version): remmina - Version 1.2.0-rcgit-15 (git n/a)
• Desktop environment (GNOME, Unity, KDE, ..): Unity
• Connecting to (OS and version): Windows 10
• Connecting via (RDP, VNC, ...): RDP
• RDP issues only, freerdp version (xfreerdp --version): This is FreeRDP version 2.0.0~dev (git n/a)

This is a feature request. I'd really like to see a way with in the Remmina gui to configure advanced options of xfreerdp such as things like rdp8/gfx, rfx, compression, etc. Even if this was a text box that you could pop cli arguments into, that'd be great. I end up using xfreerdp on the cli because I can only use the rdp8 stuff through that which is inconvenient compared to the Remmina GUI.
