Partial commit for SVY-6666, SVY-6818, SVY-6337, SVY-7028, SVY-7026.

It is not working yet. It's just a commit to merge easier with head
changes.

Still to be done: browser side refactor of components from array to
non-array, browser side impl. of custom json arrays, browser and server
side impl. of custom json object, making it work with all the changes.
Merge branch 'master' into refactor_conversions_to_9

All seems to be working now except CustomJSONObject (so half of 7028)
which is also needed to fix 7026.

Updated unit tests to work with this refactor.
Also moved some code - for tests to work - into ComponentFactory from
WebFormUI because after calling createComponent it should really have
correct properties set (just like in other clients).
