Simplified network requests & snackbars
and rewrote the component's network requests. showSimpleSnackbar, allows displaying a simple snackbar, with text and one action button, that can be clicked. doNetworkRequest is supposed to be a wrapper for the already existing post* functions. It aims to make network requests and error handling easier, by containing all the try&catch blocks and being able to show snackbars.
