Fix NPE when pasting non-text from Clipboard

When copying a link from a bookmark and then pasting it into
a textfield a NullPointerException will occur.
A ClipData.Item is not guaranteed to always contain a text string
and therefore getText() can be set to null.

Using method coerceToText() instead of getText() makes sure that
a text string is always returned.

"[+>" more icon was never shown in PhoneStatusBar

"[+>" more icon was never show in status bar because
the member variable for this icon was not initialized
from resources. This fix enables "[+>" icon to appear
in status bar when the number of indications in status
bar becomes large.
