ADD. RadRichTextBox - add support for line numbering

Support for opening word templates in RadRichTextBox

IMPROVE. RadRichTextBox - should be able to run with .NET Framework 3.5, rather than 4.0

RadRichTextBoxElement to be a custom editor of RadGridView

ADD. Export of Office 2010 dotx document templates.

ADD. RadRichTextBox - import text boxes from docx files

Currently it is not possible to control the HTML exported from RadRichTextBox and strip styles or embed them.

Currently this product cannot read the text contained in RichTextBox.

The bullets can have their own alignment. Implement import and export of this setting.

In MS Word, this alignment can be set through the Numbering dropdown -> Define New Number Format

When a table cell contains nested table, and the paragraph after the nested table is empty, this paragraph could be collapsed, as in MS Word. This gives better look to nested tables, similar to how browsers visualize nested HTML tables.
Note that the paragraph should be visualized when the caret moves the position inside the paragraph.

Currently the paragraph is visualized with its full height, making the layout different than MS Word - it appears that there are redundant space after the nested table.

- There should be a formatting symbol for the character

- Pressing Ctrl+Shift+Space should insert the character (standard MS Word shortcut)

- Import from docx should be implemented

- The symbol should be treated as a separator between words when spell-checking

Currently all tables are stuck to the let and there cannot be a text before them.
