Add ability to play different animation depend on monster hp.

Disabled for legacy servers because monster hp unknown and
compilated hp can be wrong (version <= 0).

For usage need add to action tag attribute hp="xx"
Example:
    <action name="stand" hp="50" imageset="base">
    ...
    </action>
Here 50 mean 50% of health or less.
Default action tag mean hp=100
