initial commit

Very rough and full of clutter in some places and glaring holes in
others, but it's a start!
Tour and Clearbox Fixes, general cleanup

Alphabetized tour listing on homepage, fixed public/private tour bug,
formatted tours/browse listing to match items/browse, fixed issue where
Omeka was not registering the template customizations for TourBuilder;
fixed unparsed HTML in  title problem for the Clearbox image viewer;
removed unused JS and other files/libraries; removing hard-coded
references to Cleveland as they come up.
Tour Builder: no-slug bug

adds check for empty slug, which can result in one tour overwriting
another because both have an empty slug (i.e. the same slug). Needs
further work to iron out this issue, which also applies to the title
and other fields.
TourBuilder: validation fix

Now returns an error for non-unique entries in title and slug fields.
TourBuilder: fix for delete-tour bug

Now able to delete tours
Tour Builder

Public/Featured checkboxes in tour admin now work (still not honored in
public theme browse/show templates), other minor fixes
Directory cleanup

deleted .swp files
Oops
Revert "Oops"

This reverts commit 1b3c437acd30f6eddc54474f525a03a9754f12a6.
TourBuilder: interface improvements

Adds Tours tab to admin nav, fixes labeling errors, fixes some display
bugs, hides "Add Item" button until the tour has been saved to avoid
error (this needs to be addressed in full at some point, probably with
an interface overhaul for the whole plugin).
Restrict public viewing to public tours only [#237]

Thanks to an explaination given by clioweb over at #omeka. S/he
pointed me to the way that items are handled, which led to discovery.
