Upgrades to the Grammateus user interface

An upgraded user interface has recently been posted on the OCP site. The interface now allows users to select specific chapter/verse ranges for viewing. Users can also now produce a printer-friendly version of text displayed in the main reading window. Where texts have a critical apparatus, users now click on the main-text to view variants (instead of simply mousing over the text). This last change will help the interface to be more stable in general and will also allow users to retain variants in the apparatus window while they perform mouse operations elsewhere on the screen.
