#8 add example to password attribute

[Ralf Hauser]

in order for the test specs not to become a security
issue by themselves, you might want to add the
following example to the password attribute description
in
http://aft.sourceforge.net/manual/Action%20tasks.html#elem:httpRequest:

<if>
<!-- usage:
* if the password is "abc" you can give it on
the command line:
anteater -f aft_test.xml check-website -Dpw=abc
* if the password is in the file pw.property
that is not shared (CVS),
add the line <<password=abc>> to that line and call it
anteater -f aft_test.xml check-website
-Dpw=propFile
* else you will be prompted for a password
-->
<isset property="pw"/>
<then>
<if>
<equals arg1="${pw}" arg2="propFile"/>
<then>
<loadproperties srcFile="pw.properties"/>
</then>
<else>
<property name="password" value="${pw}" />
</else>
</if>
</then>
<else>
<input message="Please enter the password"
addproperty="password" />
