CMSSIX-288: restructure CMS 6 SVN

HSTTWO-1357: Support (vertical alligned) div in Page Composer
- Added vertical div container (vbox)
- Added direction to containers (horizontal or vertical)
- Updated dropIndicator draw code, use offset instead of position, simplified api
- Added special className to new (click to refresh) items to make them stand out a bit more
- Fixed issue with mismatch between DOM element order and visual order

HSTTWO-1377 changes applied as described in jira issue. All cleanup valve logic for statefulsession has been moved to the JCRSessionStatefulConcurrencyValve.

Still one thing to improve: The jcr event observers should also listen to changes below the hst configuration (default hst:hst) : We currently do only listen to events below /content which does not capture event changes in hst configuration

HSTTWO-1328: Adding default callback handler configuration for Jetty not to leave warning message.

HSTTWO-1329 do not have implicit alias for a mount. Only when a mount has a 'hst:alias' property, the mount has an alias. Before it had an alias by default the name of the mount. This turned out to be unhandy and to restrictive

HSTTWO-1308 account for hst:isnamedrenderer and hst:isnamedresourceserver properties

HSTTWO-1327: Fixing owner link of image resources.

HSTTWO-1308: Changing the property name and comment.

HSTTWO-1308 remove the hst:isNamed as Woonsan use isNamedRenderer and isNamedResourceServer. We need to decide where in the cnd we define that something is a isNamedRenderer and isNamedResourceServer. The difficulty is that the isNamedRender seems to belong to a hst:template and the isNamedResourceServer should be on the hst:component. 
It is by far easiest in code if we add the isNamedRender boolean to the hst:component as well, however, most likely, it does not belong there. Needs to be decided

HSTTWO-1308: Prefixing only for (non-slashing-leading) relative path

HSTTWO-1308 added placeholder method getNamedRenderer() and added isNamed boolean to cnd. Did not yet implement the usage of this property

HSTTWO-1321, HSTTWO-1322 changed the alias lookup to first try to resolve a mapped alias. Furthermore, made all alias logic case-insensitive
