- added a whole bookmarks collection so one can access it from DocX and get the bookmark by name
- added a SetText method to the Bookmark so one can set the text from it using something like this: docX.Bookmarks["MyBookmark"].SetText("MyText")
- Added example BookmarksReplaceTextOfBookmarkKeepingFormat

In addition two new features: Table of contents and a way of validate if a document contains bookmarks with specified names. This is useful in applications where users can upload a template that will be populated based on form data. If this form data expects one or more bookmarks present in the document, one can now check this up front and use it to provide feedback to the user.

The following files have changes:

• DocX.cs
o Method: Addlist(string, int, ListItemType, in, bool) (I've added another paramter, bool)

This projects contains many of the examples upload on my blog.
Each time docx is released, I will update these examples so as they still work regardless of API changes.
