* Removed limitation to edit running polls
* Fixed some issues in MySQL database scheme
* Moved routine for replacing version tags from init to export target in build script
* Metadata is now written to its own table instead of a column only
* Values are saved as JSON-like structure only for certain types (like Array or Function)
* Adding custom metadata is more generic using the new HopObject methods setMetadata(), getMetadata() and deleteMetadata()
* Searching keys and values via common SQL query is much more straightforward (no JSON-like structure involved when basic types like String and Number)
* Added work-arounds for tagging problem in Story, Stories, Image and Images until Helma bug #607 is fixed
* Deprecated getData and setData methods in Metadata
* Converted most site properties to metadata
* Implemented generic framework into Site prototype
* Added basic form support to generic framework
* Added support for positionl parameters in some macros (e.g. link_macro, skin_macro, created_macro)
* Added link_filter to Global and HopObject
* Added check for "Cancel" in HopObject's onRequest()
* Had to disable display of disk usage in SysMgr due to an issue that has to be resolved, yet
* Added support for various new site preferences (at least in the form :)
* Removed some code related to Lucene search until it's clear how search will work in the future
* Added quite a lot code for backwards compatibility
* Updated database patches
* 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)
