Logic UI: Armature Actuator + general Captalizing 1st letter of UI text

- Armature Actuator now only shows the "Secondary Target" option when the Bone Constraint supports it (IK only now).
-- that may be overkill I don't know. It shouldn't slow down the UI considerably, so it should be fine. Easy to revert if needed though.

- renaming things such as "Start frame" to "Start Frame"
