Another update for the UI

[tonymanou]

Here is another update !

• Fixed filter frame's hidden state that was not restored when restoring the instance state
• Moved the filters 'hide system app' and 'filter by permission' from the settings to the filter frame
• Bigger expand icon for filter section (asked on XDA)
• Fixed alignment of the items in the filter section
• Improved the design of the filter frame (asked on XDA) : the corners are less round, the background is now a gradient
