SystemUI: Display Pie in forced immersive mode

When an app developer decides that it is needed, immersive mode can be
turned on by the app. Prior to this commit, the stock navigation bar
was always shown when it was done. This commit creates a special
immersive mode (forced immersive mode) which is enabled when an app
requests immersive mode (status bar and navigation bar can be hidden)
if the user has chosen to use Pie prior to this. This mode then makes
Pie appear instead of the stock navigation bar.

It should be noted that this also introduces a minor issue when the
user turns off the standard immersive mode as when doing so, the new
forced immersive state is enabled until the QS panel is closed/swiped
up, after which the system automatically switches over to the fully
disabled state. This is caused by the QS panel still appearing to be
immersive to the system. It can be seen on the other side of the QS
tile as it will say "Forced" for the new special immersive state and
"Disabled" for the fully disabled immersive state.

QS: Link the screen timeout tile to the settings

This commit simply makes long-pressing the back of the sleep tile (the
screen timeout selection part of the tile) start the appropriate
settings activity (Display settings). This matches the behaviour of
most other QS tiles where there are additional settings screens.

QuickSettings: Refresh RSSI tile on tap

When tapping the RSSI tile to disable mobile data, the indicator
would not show immediately because the view is not updated until
the next signal refresh.  Refreshing on tap makes more since so
that the user sees instant feedback.

Themes: Support applying components from multiple themes [1/3]

The current implementation assumes the components being passed
into the ThemeService belong to the same theme.  This patch uses
a Map instead of a List to pass in a mapping of components to
package names, allowing us to apply several components from
different themes.

Requesting a theme change now takes a Map<String, String> which
maps components to the theme package name they will be applied
from.
Example:
    Map<String, String> componentMap = new HashMap<String,String>();
    componentMap.add(ThemesColumns.MODIFIES_ICONS, "com.mytheme.blue");
    componentMap.add(ThemesColumns.MODIFIES_OVERLAYS, "com.mytheme.red");

    ThemeManager tm = (ThemeManager) contex.getSystemService(Context.THEME_SERVICE);
    tm.requestThemeChange(componentMap);
