* Renamed ImageMgr to Images
* Fiddled with more elegant context switch between Layout and Site images (still a little bit messy)
* Added getUrl and getDirectory methods to File and Image
* Moved global getPoolObj to HopObject.getFromPath
* Moved global renderImage to Image.render
* Moved global DefaultImages to Images.Default
* Moved global thumbnail constants to Image
* Moved global evalImageType to Image.validate
* Streamlined image_macro (good-bye pop-ups!)
* Added HopObject.upload_macro to support file upload form element
* Added conversion and compatibility scripts for images and layouts
* Fixed issue caused by setting a Metadata property to a Java value, e.g. java.net.URL instance becomes string without quotes. (Could this be a Rhino bug?)
* Finalized conversion of AV_USER table to simple naming scheme ("user")
* Added global getTitle() method which returns either site.title or root.sys_title
* Implemented universal HopObject.value() method
* Rededicated User.update() method since its previous functionality is now taken over by User.value()
* Restructured login and register functionalities in User and MemberMgr
* Replaced first occurrences of Exception with Error
* Introduced i18n via gettext in User and MemberMgr
* Removed getMessage() and Message in User and MemberMgr
* Added first possible implementation of global getPermission() method
* Modified code of global evalEmail() and evalURL() methods to work with Helma modules
* Simplified global sendMail() method by not throwing any MailException anymore and returning the status code only
* sendMail() now is using helma.Mail (so we can debug message output)
* Improved tag framework
* Added support for image tags
* Moved most code of StoryMgr.evalNewStory to Story.evalStory to decrease redundancy
* Added compatibility module (including drafts for database conversions)
* Moved code for topics to compatibility module
* Removed obsolete code
* Skins are attached to skinset rather than site objects
* Each site can have multiple skinsets
* Skinsets can inherit from each other
* Added subclasses of imagemgr and skinmgr that mount on root/manage
