Search inside of server folder for java runtimes

[flleeppyy]

Is your feature request related to a problem? Please describe.
Hiya, could you add functionality to the JavaPathPicker form to search in the directory of the server? Some modpack server installs come bundled with java runtimes, or allow you to install one and it'll install it into the server directory.

Describe the solution you'd like
New param to FindJavaInstallations for additional directories to search, then when calling the function from FrmInstanceEdit, pass the path of the server.

something like this? can't test but would work in theory! just combining potentialInstalledJavaLocations with the passed in args for additional directories.

public Dictionary<string, string> FindJavaInstallations(params string[] additionalDirectories)
{
	List<string> potentialInstalledJavaLocations = Globals.McssSettings.PotentialInstalledJavaLocations;
	if (potentialInstalledJavaLocations == null || potentialInstalledJavaLocations.Count <= 0)
	{
		Globals.McssSettings.ResetPotentialInstalledJavaLocations();
		return this.FindJavaInstallations(additionalDirectories);
	}

	try
	{
		List<string> searchDirectories = new List<string>(potentialInstalledJavaLocations);

		if (additionalDirectories != null)
		{
			searchDirectories.AddRange(additionalDirectories);
		}

		Dictionary<string, string> dictionary = new Dictionary<string, string>();

		// rest of the inplementation here
}

new FrmJavaPathPicker(this._logic.FindJavaInstallations(this.server.path), this.txtLocalJavaVariablePath.Value))

though, i would rearrange the code to do like

List<string> searchDirectories = new List<string>()
if (additionalDirectories != null)
{
	searchDirectories.AddRange(additionalDirectories);
}
searchDirectories.AddRange(potentialInstalledJavaLocations);

so that the passed directory is searched and appended to the results first rather than last.
