Improve display of long user profile emails in the web UI

[SilverWolf32]

On the web interface's user profile page, if you have a very long email it spills out of the infobox into the repositories section.

(I use the Arc Green theme in the screenshots, but it happens on both included themes.)

A slight tweak to the CSS in Firefox's developer tools neatly solves the problem:

.user.profile .ui.card .extra.content ul li {
	overflow: scroll;
	display: flex;
}

This scrolls to view the entire address, as you would expect.

If display: flex; is not included, it simply degrades to having the mail icon above the address, as it is now.

(I've opened a pull request for this change as well.)
