Add a search box.

Add a search box.

* src/main/java/org/glom/web/client/ui/TableSelectionViewImpl.java:
Add a TextBox for the text of a quick find.
Add getQuickFindBox(), to get the widget, and getQuickFindText() to
get the text.
setBackLink(): Add a String quickFind parameter.
* src/main/java/org/glom/web/client/ui/TableSelectionView.java
(TableSelectionView): Add getQuickFindBox() and getQuickFindText()
to the base interface, because that is how TableSelectionViewImpl is used.
* src/main/webapp/style.css: Add style for the search box and its label.

* src/main/java/org/glom/web/client/event/QuickFindChangeEvent.java:
* src/main/java/org/glom/web/client/event/QuickFindChangeEventHandler.java:
Add these files, based on the existing TableChangeEvent and
TableChangeEventHandlers.
* src/main/java/org/glom/web/client/activity/DetailsActivity.java
start(): Handle QuickFindChangeEvent, passing its quickFind text to
a ListPlace() that the user should be taken to.
* src/main/java/org/glom/web/client/activity/ListActivity.java
start(): Handle it here too and adapt the TableChangeEvent handler to
pass the extra  quickFind parameter to ListPlace.
* src/main/java/org/glom/web/client/place/ListPlace.java:
Constructor: Take an extra String quickFind parameter and store it,
returning it from a new  getQuickFind() method.
getToken(): Put the quickFind text in the URL token.
getPlace(): Parse the quickFind text from the URL token.
* src/main/java/org/glom/web/client/ui/DocumentSelectionViewImpl.ja
va: addDocumentLink(): Pass an extra  quickFind parameter to the
ListPlace constructor.
* src/main/java/org/glom/web/client/activity/TableSelectionActivity
.java: start(): Add a Change handler for the TableSelectionView's
TextBox (via its base HasChangeHandlers interface), firing the new
QuickFindChangeEvent.
setPlace(): Adapt the call to TableSelectionView.setbackLink(), to
pass the extra  quickFind parameter.

* src/main/java/org/glom/web/client/ui/ListViewImpl.java:
setCellTable(): Add a String quickFind parameter and pass it to
the ListViewTable() constructor.
* src/main/java/org/glom/web/client/ui/ListView.java: Change
setCellTable() in the base interface, because that is how ListViewImpl
is used.

* src/main/java/org/glom/web/client/ui/list/ListTable.java:
Add a String quickFind member variable.
* src/main/java/org/glom/web/client/ui/list/ListViewTable.java:
Constructor: Add a String quickFind parameter, storing it in the
base ListTable's member variable.
onRangeChanged(): Pass quickFind to the
OnlineGlomServiceAsync.getSortedListViewData() and
OnlineGlomServiceAsync.getListViewData() methods.

* src/main/java/org/glom/web/server/OnlineGlomServiceImpl.java:
getListViewData(), getSortedListViewData(): Add a String quickFind
parameter, passing it to ConfiguredDocument.getListViewData().
* src/main/java/org/glom/web/client/OnlineGlomService.java:
Change getListViewData(), getSortedListViewData() in the base interface,
because that is how OnlineGlomServiceImpl is used, via this:
* src/main/java/org/glom/web/client/OnlineGlomServiceAsync.java:
Change getListViewData(), getSortedListViewData() here too.
This class can apparently be used to asynchronously call methods on
OnlineGlomService, and GWT seems to implement that after recognizing
just the *Async name convention and the extra AsyncCallback parameters.

* src/main/java/org/glom/web/server/ConfiguredDocument.java
getListViewData(): Add a String quickFind parameter, and pass it to
ListViewDBAccess.getData().
* src/main/java/org/glom/web/server/database/ListDBAccess.java
getListData(): Add a String quickFind parameter and pass it to
getSelectQuery().
getSelectQuery(): Add a String quickFind parameter.
* src/main/java/org/glom/web/server/database/ListViewDBAccess.java
getSelectQuery(): Add a String quickFind parameter and use it with
Glom.get_find_where_clause_quick() to pass a where_clause to
Glom.build_sql_select_with_where_clause(), to actually filter the
list view results.
getData(): Add a String quickFind parameter, passing it to getListData().
* src/main/java/org/glom/web/server/database/Rela
va: getData(): Pass an empty string to getL
quickFind parameter.
