Fix for issue 1301: Addedinstance method now() to the flash statement, making it unavailable to the next action.
Start of SASS. Cleaned up some code.
More SASS. Also got rid of the 'alt' rows for syntax highlighter and just used nth-child(odd) so you don't need to keep adding/removing alt classes
Removed some silly alt stuff for syntax highlighting.
Assignment summaries are laid out less wonky now. They also display side by side if the screen is wide enough.
Tabs moved to SASS.
More UI fixes/tweaks. More code cleanup here and there.
More tweaks. (Dialogs look a bit nicer too)
Menus are less broken.
More stuff.
Added @ealona's test cases.
