Make the log username abbreviations not case-sensitive

[Awaclus]

There was a game in which I was trying to Ctrl+F the log for how many Silvers I had, but my opponent's name started with a lower case 'a' so that wasn't possible.

I'd appreciate if this was fixed.

At least in Firefox, you can make the Ctrl-F tool case sensitive. Not sure if Chrome does that, though.

It should remain case sensitive, but add more characters until there is character different not just by case.
