Use newly added java-libglom API to create queries.

Use newly added java-libglom API to create queries.

This isn't finished. I still need to stop using Strings for primary key
values in the client code.

* src/main/java/org/glom/web/server/OnlineGlomServiceImpl.java: Tell
libglom to use fake connections so that retrieving the query string will
work.
* src/main/java/org/glom/web/server/database/DetailsDBAccess.java:
* src/main/java/org/glom/web/server/database/ListViewDBAccess.java:
* src/main/java/org/glom/web/server/database/RelatedListDBAccess.java:
* src/main/java/org/glom/web/server/database/RelatedListNavigation.java:
Use the newly added libglom sql methods and classes to create the
query. Add temporary hack to convert primary value strings to Gda
Value.
