Permissions - Ask permissions only when needed

[RoadXY]

Currently when starting the app for the first time on Android Marshmallow, Domoticz immediately requests all permissions as advised by the Android guidelines for permissions here:
http://developer.android.com/training/permissions/best-practices.html#dont-overwhelm

Relative parts:
If you confront the user with a lot of requests for permissions at once, you may overwhelm the user and cause them to quit your app. Instead, you should ask for permissions as you need them.

If your app provides a tutorial, it may make sense to request the app's essential permissions at the end of the tutorial sequence.

Instead, wait until the user tries to use the feature which requires the permission and ask for the permission then.

I've fixed this matter in v0.1.142
