[Enhancement] Add toggle for Home+Lock OR just Home

[oddpawsx]

Is your feature request related to a problem? Please describe.
User request for feature to limit wallpaper setting to just home screen (preserving current lock screen as whatever it was set as before)

Describe the solution you'd like
Add a switch to the activity labeled Home+Lock (or something similar) and store the state in shared preferences to load on each app launch. Use this preference to determine which in setBitmap() call:

Int: Flags indicating which wallpaper(s) to configure with the new imagery. Value is either 0 or a combination of android.app.WallpaperManager#FLAG_SYSTEM, and android.app.WallpaperManager#FLAG_LOCK

Describe alternatives you've considered
n/a

It would also be nice to be able to use two seperate Links for Lockscreen and Wallpaper .
For example one link without Blacklist for Wallpaper and one with Blacklist for Lockscreen.
