Suggestion: Add spell descriptions to the Help tab

For mid-advanced players, it would be handy to have access to the spell description of other classes too.

For example I have never played foggernaut, or I have played cra before but I don't know details about the recent overhaul, so I don't know how their spell work. My teammates usually tell me "I don't know how dissuasive word works".

Having access to all spell descriptions would improve team cooperation in pvm/pvp fights, as well as preparing for enemy attacks in kolossium, ava, and perc/prism defenses.
