Slightly improving the English for a few alerts.

This is something I'd noticed, and I thought would be useful. 3 of the alerts for ratings could just do with tweaking.

Dislike: xxx rated your post Dislike in the thread xxx --> xxx Disliked your post in the thread xxx
Agree: xxx rated your post Agree in the thread xxx --> xxx Agreed with your post in the in the thread xxx
Disagree: xxx rated your post Disagree in the thread xxx --> xxx Disagreed with your post in the in the thread xxx

All the other alerts seem to be fine, but I'll keep a lookout for anything else that could be tweaked.

(Thanks to @Manolis Sigoulakis for helping me check all the ratings)
