Fully path assemblies

[mjkkirschner]

Purpose

http://adsk-oss.myjetbrains.com/youtrack/issue/MAGN-9567 When RTF runs some tests, it first copies addins from the revit adding folder to the working directory that the user has set, in Revit 2017, these addins now point with relatives paths to some dlls in the addin's folder. After being copied those addins throw exceptions when the paths no longer point to their assemblies correctly. This PR fixes this by parsing the revit addin files that we have copied, and making the assembly elements contain full paths using the original addin file location as the new root.

I've also updated the RTF installer binary.

@sm6srw should this change be merged to 2015/2016 branches as well?

@mjkkirschner I have not seen addin's being installed this way before, nor if this approach is supported in earlier versions of Revit. But I don't think it would hurt to also merge this 2015/2016.
