(chore) require webview for online functionality

if no current webview is found, foxmmm should revert to an offline only module manager - allowing install from storage and to remove modules, but no update checks or online repo functionality will work

quite a bit of the http stack now relies on webview and will crash or not work as well without it so better to avoid any issues

and besides, everything since at least 4.4 has webview built-in
