Improved Unicode support and tests
add JP's dynamic tests, fix for setting usig object subscripting on standalone objects
make property initializer private, update swift
Rename RealmVisualEditor to RealmBrowser in a consistent way

Also add a browser target in build.sh

The core folder is now a symlink to a versioned folder

This will allow to work on different versions of core from

Move the bin symlink into the build folder

Removes clutter from the root folder
No need to remove the bin folder now
Move build.log into the build folder

Another effort to de-clutter the root folder
