Add a default `.vscode` directory setup on project creation

[ewanharris]

When creating a new project the extension should create a .vscode directory with the following:

• settings.json to tell vscode to ignore certain folders, such as build/ (always), Resources/ (alloy only), platform/ (alloy only)
• launch.json with a basic debugger setup

For a Classic app, my .vscode/settings.json looks like this...

{
	"files.exclude": {
		"build/": true
	},
	"search.exclude": {
		"build/": true
	},
	"files.watcherExclude": {
		"build/": true
	},
}

For Alloy, my .vscode/settings.json looks like the below. I've tested with "kitchensink-v2" and it correctly hides the root "i18n", "platform", and "Resources" folders... but still reveals the same folders under the "app" subdirectory.

{
	"files.exclude": {
		"build/": true,
		"i18n/": true,
		"platform/": true,
		"Resources/": true
	},
	"search.exclude": {
		"build/": true,
		"i18n/": true,
		"platform/": true,
		"Resources/": true
	},
	"files.watcherExclude": {
		"build/": true,
		"i18n/": true,
		"platform/": true,
		"Resources/": true
	},
}

Not sure if there is a better way of doing the above without the duplication. I'll leave it to the experts. :)
