Increment version

* Fixes #14 (although detection is disabled in background processes due to the bug described in #60)
    * Added App icons and basic installed detection
    * Real Package Names Used as IDs + App Icons (INCONVENIENT FOR PREVIOUS VERSION USERS)
    * Switch to using extracted names (no custom names)

* Fixes #57

* Fixes #67

* Fixes #64

* Fixes #61

* Commented out APKMirror and added code to remove their Apps

* Updated README

* Switched to Flutter stable (causes some UI elements to switch back to the old material design style, but this will be fixed in later Flutter releases)

* BG task silently retries on network errors

* Updated screenshots
