tdf#151710 Enable enclosing of selected text with characters

This patch implements a new setting in Tools -> Options -> Writer ->
Formatting Aids -> Autocomplete -> Enclose with characters.

When this option is enabled (default), selected text is enclosed
with parentheses, square brackets, curly braces or quotation marks,
depending on which character is pressed.

For example, if the selected text is "abcd", the option is enabled and
the button for the character '(' is hit, the text is replaced with
"(abcd)".
