Made rudimentary first version of Notifications system in frontend

Added Notifications counter on Navbar, added a notifications-page.vue, listed out all notifications using v-for, nuxt-link them all using v-bind:to their respective urls.

Next up, to count all the user’s notifications with Read:false and display a badge with the count in frontend. When user clicks on a notifications you make a call to API and set Read: true, if the call was successful then you subtract -1 from counts.
