Control-U during character class creation resets bonus pool

[petchema]

Classic Daggerfall uses plain U key, but since in Daggerfall Unity the class name input field always has focus, that key would add an U character to the class name instead.

Remark: Under Linux, keyboard handling behaves a bit differently in the Unity Editor and in the Standalone Player: standalone player filters out control characters, while the editor does not, adding a "?" in the class name when Control-U is pressed. They could be filtered explicitly:

+                    }
+                }

                 // For upper only, force everything to caps
                 if (upperOnly)

but it seems less risky to just be aware of this small problem happening in the Editor only. (just tested that the problem doesn't occur under Windows).

Rereading the PR title, now I understand how confusing it was ;) Anyway, thanks for merge!
