Joomla template support

Goal

Idea is to use their templates for Aida web sites. You find a joomla template and convert it to Aida's template. Slowly we could build a
gallery of our own templates (as VW parcels or squeak packages).

Realization

• JoomlaStyle (subclass of WebStyle)
• this is an example but working joomla template (mitra)
  
• includes method images for that template
• includes CSS for that temlate
• includes framing methods for that template
  

Preparing a new template:

1. prepare a package named for example: Joomla-Mitra
2. extend JoomlaStyle to that package
3. import all template images with maintenance method importImagesFromDirectory: for instance:
   
• JoomlaStyle new importImagesFromDirectory: '/home/user/jommla-mitra/images'
4. put template's CSS into method cssJoomlaTemplate
5. adjust url links in CSS method:
   
• JoomlaStyle new adjustCSSLinks
6. reorganize framing methods if necessary - compare them with template's index-php

Installing a new template

1. Just load a prepared parcel or package, which will extend/override default template

Using Joomla templates in your app

• subclass your style class from JoomlaStyle instead of WebStyle
• this will immediatelly change behavior of pageFrameWith: title: method and therefore a joomla style will replace default Aida one
  
• adjust layout with overriding JoomlaStyle methods (see protocols page elements, elements, frame printing)
