RESOLVED - issue OPENFLEXO-344: New OR gateway presentation 
https://bugs.openflexo.com/browse/OPENFLEXO-344
Allowed OR operator to be resizable
Minimal height of annotation is 20 (for Node palette)
LOW: Smaller code for getValue()
LOW: Removed labels from document
MEDIUM: Fixed issues with boolean properties 'is...')
LOW: Increased default width of activities in the model
IMPORTANT: Updated opacity on many widgets and panels. Opacity should be
handled by the FIB "opaque" property. In some cases, in order for that
property to properly work, we force the opaque property of some
intermediary (artifact) components to false since the actual FIB
component will take care of it.
