[WIP] MetroDialogs v4

[AzureKitsune]

Todo list

• Remove SizeToContent stuff. I have no idea why that was there. See Window SizeToContent #881 because it was the temporary solution until I removed this.
• Write a simple InputDialog. If you want more features, take the code and modify it to your needs.
• Fix accented dialog's transparency.
• RequestClose works for internal dialogs too. It is now called RequestCloseAsync.
• Added UseAnimations property to disable the animations on dialogs. This does not affect the overlay animations.

FIXES #906

What does it bring new? :D

@robertstefan Bug fixes of course. I am taking suggestions for new features! 😸

[robertstefan]

MetroDialogOptions.ColorScheme = MetroDialogColorScheme.Accented;
await this.ShowMessageAsync("Application Error", "message_here");

gives this modal

MetroDialogOptions.ColorScheme = MetroDialogColorScheme.Accented;
var dialog = (BaseMetroDialog) new LoginDialogModal();
await this.ShowMetroDialogAsync(dialog);

gives this modal

What am I missing?

EDIT:
Just discovered by trial, that if i bind AccentColorBrush to the background of the control it works, but doesn't it kinda defeat the purpose of MetroDialogOptions.ColorScheme ?

@robertstefan It is something you have to handle from inside of your custom dialogs. In the ProgressDialog and MessageDialog, I handled both cases already. You simply have to do the same.

See this line as an example.

Now that explains a lot why there was such a difference :)
Thanks @Amrykid

@robertstefan No problem!

@Amrykid is there any method in the latest code from master branch that allows you to close the modal from within?

I mean, I open a modal from the main window, but in case I receive an error I want to close it and display the error message.
I have this code:

try
{
    Assembly = _driver.LoadAssembly(DatabaseConnector.SelectedValue.ToString());
    try
    {
        Connection = _driver.ExecComm(Assembly, DatabaseCommands.Connect, new Dictionary<string, dynamic>
            {
                {"user", DbUser.Text},
                {"host", DbHost.Text},
                {"password", ServerPassword.Password},
                {"enableMars", true}
            });
    }
    catch(Exception)
    {
        throw;
    }
}
catch(Exception)
{
    throw;
}

I gave it a try by passing the metrowindow as a parameter when I instantiate the modal :D but I don't think that's a good idea...

@robertstefan I don't understand. Since this is not directly related to dialogs, could we take this to IRC? You can access it directly from your browser by clicking here and typing in a name and the capcha.
