Adding option to disable smooth scrolling
Smooth scrolling is used adding the GDK_SMOOTH_SCROLL_MASK bit-flag to the remmina drawing area. The event is managed at a plugin level, at the moment only for RDP and VNC.
In RDP I have added a genral RDP settings that apply too all profiles, and a setting to disable smooth scrolling on a connection profile level.
In this way is possible to disable globally the smooth scrolling, or on a per connection profile.
In VNC, as it doesn't have global settings, I've added only on a per connection level.
Closes #2531 (closed)
