inconsistent way to handle text/html files
IzPack should have an unified way to bind text/html resources to text/html displaying panels.
For example, for a HTMLInfoPanel, we have (from the doc) :
But with InfoPanel we can only display one file (one single InfoPanel or several info panels displaying the same file), and the resource must be id'd "InfoPanel.info".
With (HTML)LicencePanel, we can only choose one file, (HTML)LicencePanel.licence.
HTMLHelloPanel behaves like HTMLInfoPanel (can choose the resource for each panel).
This is quite confusing for the user, and the doc isn't very clear on that point.
The user should be able to choose which file go to which text/html displaying panel. Having those panels behaving like the HTMLInfoPanel would solve this problem and shouldn't break existing installers (they use the default id).
