Added Finish date to tasks in the calendarpane. Using css this is currently only shown for milestone tasks, thus solving https://github.com/rpbouman/open-msp-viewer/issues/14
In addition, added experimental support for localized date formats. The idea is to render a date in a div, with separate spans inside for date parts year, month and day. By setting the navigator userLanguage (for IE) or language as a class at some higher level (currently body), we can guess the date format for that language, and then use float left / right to position the date parts as required. The date separator is selected with :after pseudo elements and css generated content.
Also, fixed a bug (div by zero) in the splitpane getRatio.
Fixed the splitpane ratio division by 0 problem.
