[Client] Chat, Masteries buggs

There are lots of buggs in the client, and they are quite annoying, and i guess is not a difficult thing to fix.

1. Masteries: here we have several buggs, first of all i guess everyone havs problems when changing masteries from one page to another in champ select screen. You select one masterie page but it dont change, or you scroll up or down and the tab gets closed. The second bugg, i dont know if this happends more often, is the next one, i do look masteries of another summoner in his profile, and in champ select screen my masteries have this summoner page names, but the points of them are still the same (mines).

2.Chat buggs: Sometimes certain summoners tend to have an Online status when they are supposed to have an "In Game" status. Game invitations not arriving, or the chart to accept the game does not appear, an several ones.

I hope you guys can fix this, thank you
