iOS CLI: Upload to AppStore fails if app contains non-alphanumeric characters

There is an issue when uploading iOS apps to the AppStore if these contains special characters. In my test-case, it was "Test!123". The underlaying issue is that we generated url schemes for the app that are not escaped. Example:

	<key>CFBundleURLTypes</key>

	<array>

		<dict>

			<key>CFBundleURLName</key>

			<string>com.appc.test</string>

			<key>CFBundleURLSchemes</key>

			<array>

				<string>test!123</string>

			</array>

		</dict>

	</array>

A simple fix is to escape the url scheme during build and be good to go. In a later major release, we could also evaluate not generating the url scheme at all, since it should be up to the developer to configure that.
