Better Support for Touch Events in Menus

Extended jQuery to create a new "clicktouch" event hook to handle both
touchstart and click events without ghosting. Changed all click events
in menus to clicktouch events. See

Added Auto-Display My Collections Capability

When someone logs in, if they logged in via the My Collections menu item
then start their session by displaying My Collections. If they logged in
via the log in icon then start their session by displaying their default
collection, which is the current behavior. Note that the user should not
go automatically to My Collections for the remainder of their log in,
even when visiting their default collection later. The only other way to
get their during their log in is by clicking on My Collections.

Added Link for Copying Tour URL to Clipboard

See https://trello.com/c/Tdqava4Z/205-share-tour-link for details.

Added links to each tour in the Tours list that provides a copyable URL
to share the tour. This required adjusting how the message pane on the
left displays.

Also:

1. Tidied up the look of each tour's small blue links.
2. Added tooltips for each tour
3. Renamed the "Tour" link to "View". Now the names of the links are
"View", "Edit" and "Link".
Changed Label for Copying Tour Link

Renamed label from "Link" to "Share" to encourage sharing tours.
