fdo#37606 SwWrtShell::SelAll(): initial support for doc starting with table

SwWrtShell::SelAll() can now detect if the body text starts with a
table, and if so, it explicitly selects the whole document, not just the
first cell of the starting table.

Also, SwCrsrShell::EndAction() now checks for this "select all and doc
starts with table" situation, and if that's the case, it activates a
special select all mode, so layout can act accordingly.
