Colorize java.lang.Character using color map's :character instead of :string

[ivan]

Thanks for Puget! It's been far more helpful than I expected.

I've made these changes because I've always had strings and characters set to different colors in IntelliJ IDEA, and I'm trying to get those same settings in Puget.

Coverage remained the same when pulling 25225b6 on ivan:character-color into 3fccd7c on greglook:master.

Glad you're liking it! The change looks good to me, but could you reopen this against develop instead? I'm following the git flow branching model; I switched the default branch over to develop so that forks will do the right thing in the future.
