To compare if two property contains the same content. The default
implementation in Property uses the persistense interface to save both
properties to string and compares the content. This may not work at the
moment if the property saves content in separate file or in binary.
Various properties have cheaper implementation to direct compare their
internal values.
Any object reference inside this function is treated as hidden to
exclude it from dependency calculation. This function allows some form
of cyclic depdenency.
Merger note: renamed from "HREF" to "HIDDENREF" to avoid confusion with
the standard "hypertext reference" use of HREF.
ONLY enabled if the Cloud Module is compiled into FreeCAD
ALL files must be saved into a Cloud Based storage
Add a Signal to the PropertyLink to enable support of external storage

PropertyLinkItem now support all major types of link property.
PropertyLinkListItem is no longer necessary, but kept for backward
compatible, which is now identical to PropertyLinkItem.
DlgPropertyLink, the link selection dialog, is now made modeless, so
that that user can select geometry sub-element directory from 3D view.
PropertyXLinkList is derived from PropertyXLinkSubList, which is
modified to provide APIs compatible to PropertyLinkList.
The only difference between the two class is in their getPyObject() to
make PropertyXLinkList output similar to PropertyLinkList in Python. In
C++, both class can accept mix of objects link with or without subname,
depending on which set of APIs are used.
* Create new class PropertyLinkBase as the common parent class for all
type of links. See the class document for details of its API.
* Added new link scope 'Hidden' that is ignored during normal object
dependency calculation, but still keep tracks of object remove,
relabel, etc.
* There is a new concept called 'Shadow subname' introduced in this
patch, which will only be meaningful in future topological naming
feature. See [here](https://git.io/fjXKR) for more details.
* DocumentObject added a new API adjustRelativeLink() and a helper
resolveRelativeLink() function.
+ some are doxy others are just comment code.
+ some minor whitespace and grammatical tweaks.
+ app/SCL/* typos have also been submitted upstream (https://github.com/stepcode/stepcode/pull/366). So it's ok to merge them in to master.
