Add icons to nav drawer items and improve their title text

I've added icons to items in the navigation drawer and made the titles a little bit larger. Other than that, I added 5dp of padding to name field in profile layout. However, it looks like I unconsciously pressed Ctrl + Shift + F so the diff looks like a huge mess. The change was an addition of a single line though...

Here is a screenshot of how it looks
