Support saving settings in the active profile rather then globally

[beqabeqa473]

from #nvdaaddons/issues/12

When you swap your language preferences, or set a new language from the options page, the new selection won't saved on current active profile (if exist). But rather it saves and uses them globaly all the time.
steps to produce

1. Create multiple profiles:
2. Set source and target language from settings panel
3. Activate a profile
4. Repeat 2 with two new languages.
5. Check, Your main settings also changed.
   I will create a pull request to show how I fixed it, but it is probably a very bad way of solving this problem. So please track if there's anything wrong with nvda unless this is a new feature, even so let's add it as a personaliozed feature and let users select if they wanna use settings globaly or not.
