[AppPreferences] store should accept string, number, boolean

[EbilPanda]

as stated in the title - AppPreference-Plugin accepts string, number, boolean as inputs, as stated here

currently it only accepts string as keys and value, so if I define an value (e.q. boolean -> toogle-type in app-settings.json) and want to change it in code, the saved type will be changed to string and the preference-screen will not work anymore because the type is not as expected

solution:

change

store(dict: string, key: string, value?: string): Promise<any>;

to

store(dict: string, key: string|number|boolean, value?: string|number|boolean): Promise<any>;

(key must be same because of overloading...)
