Finished "Loading Status" feature

I finished the "loading Status" feature. It seemed hard, but was easy. I just created a Label. The text of the label is set to "loading" when we make a connection to the database and is clear within the onSuccess method which handles data returned from the database.

The "loading" widget was added to each drop-down list and on the search button.

I changed all of the status of the "Issues" listed on the Issues sections. Before we used the Issues section basically for task assignments. But now I think the Issues section is one the a good software engineering tool. In addition to assigning tasks, we can report issues, enhancements. After an issue is finished and new changes are committed, we change the issue's status to fixed. We then verify if the new changes work. If they are, then the status of the issue is change to "verify".

In this way, we can manage and keep track of issues more efficiently.
