Also remove the duplicate ic_menu_delete.xml and fix up places where it
was used.

Test: manual
Change-Id: I23ede37b7cdf9bea59b44cd0f817bf0ad0cd1d69
Updated the importance seekbar to use colorAccent instead of a hardcoded
color.
Refactored the various gear icons to all use ic_settings (a rename of
ic_bt_config). Deleted the png version (ic_sysbar_quicksettings).
Cleaned up the add icon. Now there are two vector drawables (one white,
one tinted with the accent color). Deleted the existing pngs and updated
the usages to use one of the two vector drawables. Deleted the theme
attr for ic_menu_add that had no usages.
