Fix default bmls

[herwinvw]

• better example of proc animation [fixed]
• gaze and speech is broken
• gaze: absolute: no retraction [fixed]
• gaze: dynamic: no retraction [fixed]
• gaze: persistence: [no longer needed, removed]
• gesture, greta: [fixed]
• pose: [fixed]
• does posture work? What does posture even mean in BML 1.0?

procanimation alternative:

<bml xmlns:bmlt="http://hmi.ewi.utwente.nl/bmlt" xmlns="http://www.bml-initiative.org/bml/bml-1.0" id="bml1">
  <bmlt:procanimation name="headbob" id="hb1">   
    <bmlt:parameter name="amountA" value="0.1"/>
    <bmlt:parameter name="amountB" value="0.1"/>
    <bmlt:parameter name="repeats" value="3"/>
  </bmlt:procanimation>  
</bml>

Improved gaze and speech:

<!--
A fragment of aligned verbal and nonverbal behavior

-->
<bml xmlns="http://www.bml-initiative.org/bml/bml-1.0"  xmlns:bmlt="http://hmi.ewi.utwente.nl/bmlt" id="bml1">
<speech id = "bluespeech" start="gaze2:end">
  <text>I'm staring at the blue cube.</text>
    </speech>
    <speech id = "greenspeech" start="gaze1:start">
  <text>Look! A green sphere.</text>
    </speech>
    <speech id = "bluespeech2" start="gaze1:end">
  <text>Looking at the blue cube again.</text>
    </speech>
    <gaze id="gaze1" bmlt:dynamic="true" start="4" ready="5" relax="6" end="7" influence="NECK" target="greensphere"/>      
    <gazeShift id="gaze2" start="1" end="2" influence="NECK" target="bluebox"/> 
</bml>

This has some twitch in movement though...
