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.
