Updates to v3.6-pre / v1.2-pre

-= Re-designing of UI Controls (Focus on WPF) =-

New Features / Resolved Issues
 - Introduces FlyleafHost Renderer D3D Surface (WPF VideoView's replacement and Flyleaf's for Winforms)
  * Early and fast initialization of handles and renderer which will also resolve several issues (related to #204)
  * Adds Attach / Detach functionality
  * Self Drag Move also on attach mode (within the host's owner bounds)
  * Drag n Drop Swap between FlyleafHosts (Shift + Drag)
  * Custom non-borders resizable windows both on attach and detach mode
  * Better UI Performance overall (including Swaps and Switching between Normal to Full Screen)
  * Adds Z-order surfaces support (related to #149)
  * Adds support for WPF Windows to the Renderer in addition to WinForms UserControl
  * Resolves several issues when the host's rectangle was clipped (related to #170)

 - Introduces FlyleafME WPF Media Element Control (WPF Flyleaf Control replacement)
  * Updated with the new FlyleafHost and gains better performance
  * Code clean-up and styles to allow easier override and customization
  * Early initialization and respect to the provided configuration (such as Activity Timeout, UI Refresh, Key bindings etc.)

 - Code clean-up and performance improvements
 - Resolves several issues with DPI  (related to #197)

Breaking Changes
 * VideoView has been renamed to FlyleafHost
 * Flyleaf (WPF Control) has been renamed to FlyleafME (Media Element) and does not require a FlyleafHost as it was required previously with the VideoView (it derives from it)
 * Player.IsFullScreen, Config.Player.ActivityTimeout, Config.Player.MouseBindings and Config.Player.KeyBindings.(Enabled/FlyleafWindow) has been transferred to FlyleafHost (see .cs)
 * Player.ActivityMode has been removed (its the same as ActivityTimeout=0) however Player.Activity.IsEnabled to temporary turn it on/off
 * Swap has been removed as you can now set directly the Players to FlyleafHosts

Solutions Changes
 * FlyleafPlayer (WPF Control) (WPF) [Demo/Sample Release] has been updated with new style based on FlyleafME
 * FlyleafPlayer (WPF Control) (WinForms) has been removed and it will be reviewed if required in the future
 * FlyleafPlayer has been removed as a new repository will be created soon
 * WpfFlyleafHost new Test (sample) added for the new FlyleafHost control (ideal for beta testers)
 * Utils and Logger has been transferred to new folder under Utils
 * Forces C# lang ver 7.3 to make sure everything is compatible with .net framework
