Add error checking code in case statusbar plugin or database cannot be
opened.
The animation for stamp deletion now works.

It is achieved by pure css3 transition. The html is modified to not use
jquery mobile grids. It instead uses absolute position and manually
transform them to create grid like looks. This enables the deletion
animation to be achieved with ease. With the method, the stamp box dom
needs to be deleted from the html and add again to the end of the page.
This in turn leads to the event handling where event can no longer bind to
the stamp doms but use the ui-content dom as delegation.
