Modify config to support app specific themes [1/4]

Summary of Changes
1. The configuration now supports each app to have their own theme.
Each theme can include icons, styles (ie overlays) and font.

2. The theme config is serialized into a json string and stored
in secure settings.  This entry consolidates what was previously 3 separate
keys (style, icon, font) into a single field.

3. 'CustomTheme' was renamed to 'ThemeConfiguration'.

Note: This commit is for the configuration. Additional work needs to be done to
the framework and UI to support app specific themes.

Allow specifying a theme when creating a Context

A Context normally loads the resources associated with the given
package that this context is for.  This patch allows us to specify
a theme we want attached to a given context's resources.

Use systemui's applied theme for notifications.

Notifications contain RemoteViews which are inflated using the
application's context for which this notification belongs to.  This
can look out of place if SystemUI is using a different theme than the
rest of the system.

This patch will use SystemUIs theme when inflating the RemoteViews,
giving us a more consistent look in the notification drawer.

Fix thumbnail bug

When there was no thumbnail for a given image, the getThumbNail() convenience
method could return a previously-returned thumbnail instead of null.

HOVER: Respect screen limits when adding view

As for what @Decad3nce reported here http://review.cyanogenmod.org/#/c/66654/
we shouldn't keep FLAG_LAYOUT_NO_LIMITS so view doesn't exceed the screen limits.

Thank you Adnan :)
