[Seaside] ShoreComponents demo

[Pavel Krivanek]

Hi all,

I have updated ShoreComponents demonstration page
(http://shorecomponents.seasidehosting.st). The most important new in
latest versions is ShoreLiveTable with sorting and grouping rows by
multiple columns, row data quick preview, rows selecting and actions
with selected rows. Everything is Ajax based. This component uses
single Ajax callback per column for all rows so it's quite regardful
of server load.
