Summary: fix for bidi (TLF) inputtext onchange event

Overview:
I found what looks like a more approved way to get onchange events for TLF
inputtext
I had to make a custom EditManager so we can override the "doOperation" method
to discover when the
user edits text field
Details:
use the EditManager.doOperation method to send a Event.CHANGE event, which is
what the old
TextField sent.
We need to use a different mechanism in LzTextSprite to get the text
field height than we were using with TextField; we have a hack in
there now which shoves a test string into the field and measures it.
In the TLFtextField, that messes up focus. But luckily there is
a cached text height value we can use.
Tests:
+ examples/components/bidi_component_sampler.lzx
edittext field should work properly now, no errors when entering text
test/tlf/focus-input.lzx:
type into the RTL field, and see that each keystroke or edit command is
mirrored in the
text field below, showing that onchange/ontext events are working for TLF text
field
other test case:
<canvas width="100%" height="80%" >
<view id="s1" x="20" y="20" hasdirectionallayout="true"
layout='spacing:10'>
<edittext width="200" text="disabled" enabled="false"/>
<view>
<inputtext x='4' y='4' id='i1' width='200'
bgcolor='#cccccc'>input text</inputtext>
</view>
<edittext id='e1' width="200" text="XX YY ZZ"/>
</view>
<text x='800' y='60' text="${'i1: '+i1.text}"/>
<text id="cons" multiline="true" x="800"/>
<handler name="onidle" reference="lz.Idle">
cons.setAttribute('text', 'focus: '+lz.Focus.getFocus());
</handler>
</canvas>
