QoL improvement: mouse hover popup on linked icons

Currently when you hover the mouse over any of the champion/summoner spell/item icons, you get nothing. Not even a little bit of ALT text saying the name of what it is.

Don't know {{summoner:17}} is called Garrison? Too bad. Boards won't tell you.

Want to know the stats on ? Too bad. Boards won't tell you.

Who's this guy? Boards won't tell you.

It's a simple change, but one that would benefit us greatly, particularly when it comes to items if people are discussing builds.
