* ava: Fix exit dialog while guest is running.
There is currently an issue while a game runs, the content dialog creation method check if `IsGameRunning` is true to show the popup.
But the condition here is wrong (`window` is null) so it throw a NullException silently in `Dispatcher.UIThread`.
This is now fixed by using the right casting.
* improve condition
* Fix spacing
* memory: Check results of pinvoke calls
* Increase vm.max_map_count when running Ryujinx
* Add SupportedOSPlatform attribute for WindowsApiException
* Revert increasing vm.max_map_count via script
* Add LinuxHelper to detect and increase vm.max_map_count
With GUI dialogs, this should be a bit more user-friendly.
* Supply arguments as a list to RunPkExec
* Add error logging in case RunPkExec() fails
* Prevent Gtk from crashing
* UI: Move ApplicationContextMenu in a separated class
This PR remove duplicated code related to the context menu on the Application list/grid by create a control for the menu which include related handler.
I've renamed "GameList/GameGrid" by "Application" for consistencies. And I've removed all uneeded field from the project file too.
While I cleaned up things, I've found an issue about purging Ptc/Shader cache, both methods list files even if the user say "No", shader cache is purged even if the user say "No". It's fixed.
