Added jfxrt.jar to CoreLibs and removed wrapped jfxrt.jar from Timeline
module. Also set sync=false in build.xml in CoreLibs so that jfxrt.jar
would not be removed by ivy.
Added calls to PlatformUtil.getOSFilePath(macfile) so that the mactime file
path will be quoted as the path could contain spaces which causes problems.
Fixed bug where months that contained no data were not being displayed.
Added 'Beta' to both the timeline window title and the 'Make Timeline' menu
entry.
